Abstract
BACKGROUND Pulmonary infection is a major cause of morbidity and mortality in immunocompromised patients, in whom diagnostic yields of cone-beam computed tomography (CBCT)-guided percutaneous transthoracic needle biopsies (PTNBs) have not been evaluated so far. PURPOSE To evaluate diagnostic yields and complications of CBCT-guided PTNBs in immunocompromised patients. MATERIAL AND METHODS From January 2015 to January 2018, 43 patients (25 men, 18 women; mean age 54.1 ± 16.4 years) who were suspected of having pulmonary infections were included in this retrospective study. Electronic medical records and radiologic studies were reviewed, including the underlying medical status, information on target lesions, PTNB procedural factors, and pathologic results. Logistic regression was performed to explore factors related with post-PTNB complications. RESULTS Among 43 patients, specific causative organisms or family of organisms were identified by PTNBs in 16 patients (37.2%). The most common causative organism was fungus (10/16, 62.5%), while bacterial infection was pathologically proven only in one patient (6.3%). Clinically significant change in management occurred in 12 of 43 patients (27.9%). Post-PTNB complications developed in 12 patients (27.9%; pneumothorax [n = 6] and hemoptysis [n = 6]) without PTNB-related mortality. Lower lobar location (odds ratio [OR] = 0.07, P = 0.006) was related with post-PTNB pneumothorax, while lower platelet counts (≤127 × 103/µL) were associated with post-PTNB hemoptysis (OR = 9.82, P = 0.025). CONCLUSION CBCT-guided PTNBs revealed microbiological pathogens in 37.2% of immunocompromised patients and led to subsequent clinical actions in 27.9% of patients. Post-PTNB complications occurred in 27.9% of patients, and it might be necessary to perform PTNBs more carefully in immunocompromised patients with lower platelet counts.

Abstract
BACKGROUND AND PURPOSE Collateral assessment using CT angiography is a promising modality for selecting patients for endovascular thrombectomy (EVT) in the late window (6-24 hours). The outcome of these patients compared with those selected using perfusion imaging is not clear. METHODS We pooled data from seven trials and registries of EVT-treated patients in the late-time window. Patients were classified according to the baseline imaging into collateral imaging alone (collateral cohort) and perfusion plus collateral imaging (perfusion cohort). The primary outcome was the proportion of patients achieving independent 90-day functional outcome (modified Rankin Scale 'mRS' 0-2). We used the propensity score-weighting method to balance important predictors between the cohorts. RESULTS In 608 patients, the median onset/last-known-well to emergency arrival time was 8.8 hours and 53.2% had wake-up strokes. Both cohorts had collateral imaging and 379 (62.3%) had perfusion imaging. Independent functional outcome was achieved in 43.1% overall: 168/379 patients (45.5%) in the perfusion cohort versus 94/214 (43.9%) in the collateral cohort (p=0.71). A logistic regression model adjusting for inverse-probability-weighting showed no difference in 90-day mRS score of 0-2 among the perfusion versus collateral cohorts (adjusted OR 1.05, 95% CI 0.69 to 1.59, p=0.83) or in a favourable shift in 90-day mRS (common adjusted OR 1.01, 95% CI 0.69 to 1.47, p=0.97). CONCLUSION This pooled analysis of late window EVT showed comparable functional outcomes in patients selected for EVT using collateral imaging alone compared with patients selected using perfusion and collateral imaging.

Abstract
CONTEXT Recent years show a sharp increase in research on opioid use among cancer survivors, but evidence syntheses are lacking, leaving knowledge gaps. Corresponding research needs are unclear. OBJECTIVES To provide an evidence synthesis. METHODS We searched PubMed and Embase, identifying articles related to cancer, and opioid prescribing/use published through September 2020. We screened resulting titles/abstracts. Relevant studies underwent full-text review. Inclusion criteria were quantitative examination of and primary focus on opioid prescribing or use, and explicit inclusion of cancer survivors. Exclusion criteria included end-of-life opioid use and opioid use as a secondary or downstream outcome (for intervention studies). We extracted information on the opioid-related outcome(s) examined (including definitions and terminology used), study design, and methods. RESULTS Research returned 16,591 articles; 296 were included. Only 22 of 296 studies evaluated an intervention. There were 105 studies evaluating outcomes indicative of potentially high-risk, nonrecommended, or avoidable opioid use, e.g., continuous use-described as chronic use, prolonged use, and persistent use (n = 17); use after completion of curative-intent treatment-described as chronic opioid use, long-term opioid use, persistent opioid use, prolonged opioid use, continued opioid use, late opioid use, post-treatment opioid use (n = 27); use of opioids concurrent with other potentially high-risk medications (n = 13), and opioid misuse (n = 14). CONCLUSIONS We found lack of consistency in the measurement of and terms used to describe similar opioid use outcomes, and a lack of interventional research targeting well-documented patterns of potentially nonrecommended, potentially avoidable, or potentially high-risk opioid prescribing or use.

Abstract
BACKGROUND To analyse the clinical characteristics of COVID-19 with acute ischaemic stroke (AIS) and identify factors predicting functional outcome. METHODS Multicentre retrospective cohort study of COVID-19 patients with AIS who presented to 30 stroke centres in the USA and Canada between 14 March and 30 August 2020. The primary endpoint was poor functional outcome, defined as a modified Rankin Scale (mRS) of 5 or 6 at discharge. Secondary endpoints include favourable outcome (mRS ≤2) and mortality at discharge, ordinal mRS (shift analysis), symptomatic intracranial haemorrhage (sICH) and occurrence of in-hospital complications. RESULTS A total of 216 COVID-19 patients with AIS were included. 68.1% (147/216) were older than 60 years, while 31.9% (69/216) were younger. Median [IQR] National Institutes of Health Stroke Scale (NIHSS) at presentation was 12.5 (15.8), and 44.2% (87/197) presented with large vessel occlusion (LVO). Approximately 51.3% (98/191) of the patients had poor outcomes with an observed mortality rate of 39.1% (81/207). Age >60 years (aOR: 5.11, 95% CI 2.08 to 12.56, p<0.001), diabetes mellitus (aOR: 2.66, 95% CI 1.16 to 6.09, p=0.021), higher NIHSS at admission (aOR: 1.08, 95% CI 1.02 to 1.14, p=0.006), LVO (aOR: 2.45, 95% CI 1.04 to 5.78, p=0.042), and higher NLR level (aOR: 1.06, 95% CI 1.01 to 1.11, p=0.028) were significantly associated with poor functional outcome. CONCLUSION There is relationship between COVID-19-associated AIS and severe disability or death. We identified several factors which predict worse outcomes, and these outcomes were more frequent compared to global averages. We found that elevated neutrophil-to-lymphocyte ratio, rather than D-Dimer, predicted both morbidity and mortality.

Abstract
PURPOSE MR temperature monitoring of mild radiofrequency hyperthermia (RF-HT) of cancer exploits the linear resonance frequency shift of water with temperature. Motion-induced susceptibility distribution changes cause artifacts that we correct here using the total field inversion (TFI) approach. METHODS The performance of TFI was compared to two background field removal (BFR) methods: Laplacian boundary value (LBV) and projection onto dipole fields (PDF). Data sets with spatial susceptibility change and B 0 -drift were simulated, phantom heating experiments were performed, four volunteer data sets at thermoneutral conditions as well as data from one cervical cancer, two sarcoma, and one seroma patients undergoing mild RF-HT were corrected using the proposed methods. RESULTS Simulations and phantom heating experiments revealed that using BFR or TFI preserves temperature-induced phase change, while removing susceptibility artifacts and B 0 -drift. TFI resulted in the least cumulative error for all four volunteers. Temperature probe information from four patient data sets were best depicted by TFI-corrected data in terms of accuracy and precision. TFI also performed best in case of the sarcoma treatment without temperature probe. CONCLUSION TFI outperforms previously suggested BFR methods in terms of accuracy and robustness. While PDF consistently overestimates susceptibility contribution, and LBV removes valuable pixel information, TFI is more robust and leads to more accurate temperature estimations.

Abstract
Treatment with endovascular therapy in the extended time window for acute ischaemic stroke with large vessel occlusion involves stringent selection criteria based on the two landmark studies DAWN and DEFUSE3. Current protocols typically include the requirement of advanced perfusion imaging which may exclude a substantial proportion of patients from receiving a potentially effective therapy. Efforts to offer endovascular reperfusion therapies to all appropriate candidates may be facilitated by the use of simplified imaging selection paradigms with widely available basic imaging techniques, such as non-contrast CT and CT angiography. Currently available evidence from our literature review suggests that patients meeting simplified imaging selection criteria may benefit as much as those patients selected using advanced imaging techniques (CT perfusion or MRI) from endovascular therapy in the extended time window. A comprehensive understanding of the role of imaging in patient selection is critical to optimising access to endovascular therapy in the extended time window and improving outcomes in acute stroke. This article provides an overview on current developments and future directions in this emerging area.

Abstract
Background: Endovascular treatment of abdominal wall hematomas (AWHs) has been increasingly used when conservative treatments were not sufficiently effective, and it is often preferred to surgical interventions. The aim of our study was to evaluate the safety and technical and clinical success of percutaneous transarterial treatment of AWH and to evaluate the efficacy of blind embolization compared to targeted embolization. Materials and Methods: We retrospectively enrolled 43 patients (23 men and 20 females) with spontaneous AWH who underwent digital subtraction angiography (DSA) and embolization, focusing on the presence of signs of bleeding at pre-procedural CT-Angiography (CTA) and at DSA. Furthermore, we divided patients into two groups depending on blind or targeted embolization approaches. Results: The mean age of the study population was 71 ± 12 years. CTA revealed signs of active bleeding in 31 patients (72%). DSA showed signs of active bleeding in 34 patients (79%). In nine patients (21%), blind embolization was performed. The overall technical success rate was 100%. Clinical success was achieved in 33 patients (77%), while 10 patients (23%) rebled within 96 h, and all of them were re-treated. No major peri-procedural complication was reported. The comparison between blind and targeted embolization showed no statistically significant differences for characteristics of groups and for clinical success rates (78% and 77%, respectively, −p = 0.71). The technical success was 100% in both groups. Conclusions: Our study confirms that transarterial embolization is a safe and effective option for the treatment of spontaneous AWHs, and it suggests that the efficacy and safety of blind embolization is comparable to non-blind.

Abstract
Chronic peritoneal dialysis (PD) is an underutilized renal replacement therapy in treating end-stage renal disease that has several advantages over hemodialysis. The success of continuous ambulatory PD is largely dependent on a functional long-term access to the peritoneal cavity. Several methods have been developed to place the PD catheter using both surgical and percutaneous techniques. The purpose of this article is to describe the percutaneous techniques using fluoroscopy guidance and peritoneoscope method. While fluoroscopic method uses fluoroscopy guidance and a guidewire to place the PD catheter, the peritoneoscopic technique utilizes a needlescope to directly visualize the peritoneal space to avoid adhesions and omentum during catheter placement. These percutaneous approaches are minimally invasive procedures that can be performed on an outpatient basis without the need for general anesthesia.

Abstract
To evaluate the usefulness of commercially available scatter reduction drapes in mitigating staff exposure in interventional radiology and the potential harmful effects of drape malpositioning in terms of exposure levels to both patients and staff. An anthropomorphic phantom was irradiated on an angiography device under three scenarios: no drape and correct and incorrect drape positioning. Different levels of incorrect drape positioning relative to the field-of-view (FOV) were evaluated: slight, mild and severe. Real-time dosimeter systems (positioned on the operator's eye, chest and thyroid) were used to evaluate accumulative doses and dose rates. Different obstruction levels were evaluated and compared to the observer's perception. Additionally, patient exposure was evaluated for all scenarios using a dose area product (DAP). Up to a mild obstruction, by using the drape a dose reduction of up to 86% was obtained while a severe obstruction produced a 1000% increase in exposure, respectively for all dosimeter positions compared to the use of no drape. A similar order of magnitude was observed for patient exposure. Good agreement was obtained for the observer perception of the FOV obstruction up to 25% of the FOV; for larger obstructions, an overestimate of the obstruction was observed. Patient lead drapes can reduce staff doses in interventional radiology procedures even when mildly malpositioned and obscuring the FOV. Special attention to protective drape positioning is necessary, since the severe obstruction of the FOV results in a large increase in both operator and patient exposure.

Abstract
The aim of this study was to characterize the branching pattern and morphology of the superior mesenteric artery (SMA), and also to create a new SMA classification, which seems necessary for clinicians performing surgery in this anatomical area. The anatomical variations in the branching patterns of the SMA were examined in 30 cadavers fixed in 10% formalin. Morphometric measurements were then obtained twice by two researchers. In the proposed classification system, Type I, characterized by all normal branches - inferior pancreatoduodenal artery, ileocolic artery, right colic artery, middle colic artery and intestinal arteries - occurred in 53.33% of the specimens. Type II, characterized by absence of the inferior pancreatoduodenal artery, was present in 26.67%. Type III, characterized by absence of the right colic artery, was present in 3.33%. Type IV, characterized by a common trunk for the inferior pancreatoduodenal artery and middle colic arteries, was observed in 3.33%. Type V, characterized by an aberrant hepatic artery and absence of the inferior pancreatoduodenal artery, was observed in 13.33%. The origin of the SMA was at the Th12/L1 level in 10% of cases, at L1 in 43.33%, at L1/L2 in 36.67%, and at L2 in 10%. The SMA is characterized by high morphological variability, the variants being associated with distinct clinical aspects. The introduction of a new, structured, anatomical classification seems necessary for all clinicians.

Abstract
An intervention radiology (IR) unit collected cardiac arrest data between January 2014 and July 2020. Of 344,600 procedures, there were 23 cardiac arrest patients (0.0067%). The patient data was compared to a representative sample (N = 400) of the IR unit to evaluate the incidence and factors associated with cardiac arrest during IR procedures. Age, procedure urgency, American Society of Anesthesiologists (ASA) physical status, procedure type, and underlying medical conditions were identified as valuable predictors of a patient’s susceptibility to cardiac arrest during an IR procedure. The proportion of pediatrics was higher for cardiac arrest patients, and most required immediate procedures. The distribution of high ASA physical status (III or greater) was skewed compared to that of the non-cardiac arrest patients. Vascular procedures were associated with higher risk than non-vascular procedures. The patients who underwent non-transarterial chemoembolization arterial procedures demonstrated relative risks of 4.4 and 11.7 for cardiac arrest compared to biliary procedures and percutaneous catheter drainage, respectively. In addition, the six patients (26.1%) who died before discharge all underwent vascular procedures. Relative to patients with acute kidney injury, patients with malignancy, hypertension, and diabetes mellitus demonstrated relative risks of 3.3, 3.4, and 4.8 for cardiac arrest, respectively.

Abstract
Background Transesophageal echocardiography (TEE) is useful in the assessment and procedural monitoring of congenital heart disease (CHD) with a relatively low complication rate in humans. Objectives To evaluate the safety of TEE and report complications in dogs. Animals Forty client‐owned dogs with CHD. Methods Prospective observational study including gastroesophagoscopy before and after TEE imaging. TEE was planned with a GE 6VT‐D adult probe in dogs weighing ≥4 kg and a GE 10T‐D microprobe alternating with an intracardiac echocardiography probe placed in the esophagus in dogs <4 kg. Difficulties with probe placement, probe interference and TEE probe imaging times were recorded. Dogs were monitored in the recovery period after TEE using an established nausea scoring system. Results New gastroesophageal abnormalities were identified after TEE in 4 dogs including 4 areas of mucosal damage involving <25% of the lower esophageal sphincter (n = 4) and 1 lesion at the heart base (n = 1) and were not attributed to longer imaging times or a specific probe. Lesions identified before TEE in 4 dogs remained unchanged after TEE. The 6VT‐D probe could not be placed in 1 dog with enlarged tonsils, and it obstructed fluoroscopic views in 3 dogs. The probes did not compress any structures in dogs in which fluoroscopy was performed (n = 20). Four dogs had evidence to suggest nausea after the procedure. Conclusions and Clinical Importance While major complications remain possible, complications in this study were mild and few in number. Dog size and probe characteristics are factors to consider when performing TEE.

Abstract
Objective To present our clinical experience with percutaneous antegrade ureteral
stenting. Materials and Methods This was a single-center retrospective study in which we reviewed the
electronic medical records of patients who underwent percutaneous
image-guided antegrade ureteral stenting between January 2016 and August
2020. We evaluated 90 patients (48 men). The mean age was 61.4 ± 15
years (range, 30-94 years). Patients were divided into two main groups:
those with malignant neoplasms; and those with non-neoplastic disease.
Technical and clinical success of the procedure were defined, respectively,
as maintenance of the patency of the urinary tract, with a reduction in the
degree of hydronephrosis, and as a reduction in the level of nitrogenous
waste. Postprocedural complications were categorized as major or minor
according to the CIRSE classification. Results The study sample comprised 150 antegrade stenting procedures performed in 90
patients, most of whom had previously undergone retrograde stenting that was
unsuccessful. The stenting was bilateral in 60 patients and unilateral in
30. Technical success was achieved in 143 (95.3%) of the procedures, whereas
seven procedures (4.6%) were unsuccessful. Failed procedures were
characterized by inability to place a stent or migration of a stent after
its placement. Complications occurred in 12 (8.0%) of the procedures. Of
those 12 complications, two were classified as major (bleeding) and 10 were
classified as minor (lumbar pain or infection). The most common techniques
used were the over-the-wire technique and the modified technique (in 58.0%
and 42.0% of the cases, respectively). In seven cases (4.7%), a nephrostomy
tube was inserted. Conclusion Percutaneous antegrade ureteral stenting is a safe, effective method for the
management of ureteral injuries and obstructions, due to malignant or benign
causes, when the retrograde approach has failed.

Abstract
OBJECTIVES Successful placement of a peripheral intravenous catheter (PIVC) on the first attempt is an important outcome for difficult vascular access (DVA) patients. This study compared standard technique, ultrasonography (USG), and near-infrared light (NIR) in terms of success in the first attempt in patients with DVA. METHODS This was a prospective, randomized controlled study. The study was conducted in a tertiary care hospital. Emergency department patients who describe DVA history, have no visible or palpable veins, and were assessed by the nurse to have a difficult PIVC were included to study. The PIVC procedure was performed on patients by standard, USG, or NIR device techniques. For all approaches, the success of the first attempt was the primary aim. Total procedure time, the total number of attempts, and the need for rescue intervention were secondary aims. RESULTS This study evaluated 270 patients. The first attempt success rates for USG, standard, and NIR methods were 78.9%, 62.2%, and 58.9%, respectively. The rate of first attempt success was higher in patients who underwent USG (USG versus standard, P = .014; USG versus NIR, P = .004; standard versus NIR, P = .648). The total median (IQR) procedure time for USG, standard, and NIR methods was 107 (69-228), 72 (47-134), and 82 (61-163) seconds, respectively. The total procedure time was longer in patients undergoing USG (standard versus USG, P <.001; NIR versus USG, P = .035; standard versus NIR, P = .055). The total median (IQR) number of attempts of USG, standard, and NIR methods were 1 (1-1), 1 (1-2), and 1 (1-2), respectively. A difference was found among the groups regarding the total number of attempts (USG versus NIR, P = .015; USG versus standard P = .108; standard versus NIR, P = .307). No difference was found among groups in terms of the need for rescue methods. CONCLUSION It was found that USG increases the success of the first attempt compared with the standard method and NIR in patients with DVA.

Abstract
Shoulder pain is an extremely common condition. The painful shoulder may be the result of a wide spectrum of underlying pathological conditions, including calcific tendinopathy of the rotator cuff, subacromial-subdeltoid bursitis, acromioclavicular or glenohumeral arthritis, tenosynovitis of the long biceps tendon, rotator cuff lesions, and many other less common conditions. Ultrasound imaging is an effective tool for the diagnosis and also for the image guidance of treatment of the majority of these conditions. Several ultrasound-guided procedures are effective for pain relief, such as percutaneous irrigation, intra-bursal or intra-articular drugs injection, fluid aspiration, neural block. This review article aims to summarize and discuss the most common treatment possibilities with ultrasound guidance for the painful shoulder.

Abstract
BACKGROUND When antegrade ureteral intervention fails due to severe ureteral stricture or tortuosity, a longer sheath can be used to facilitate ureteral catheterization. PURPOSE To evaluate the feasibility and effectiveness of the use of a long sheath in antegrade ureteral stent placement after failure of antegrade ureteral stent placement using a short sheath. MATERIAL AND METHODS Among 1284 procedures in 934 patients who received ureteral stent placement, a long sheath was used after stricture negotiation failure using a short sheath in 57 (4.4%) procedures in 53 patients. The data of these 53 patients were retrospectively reviewed. RESULTS The most common reasons for long sheath use were failure of balloon catheter (59.6%) or guidewire (29.8%) advancement across the stricture. Technical success, successful stricture negotiation after using a long sheath, was achieved in 50/57 (87.7%) procedures. In two of seven failed procedures, an additional TIPS sheath was used and the technical success rate improved to 91.2% (52/57). The technical success rate was significantly higher in the patients who have failed balloon catheter advancement (97.1%, 33/34) than the patients who have failed guidewire advancement (64.7%, 11/17) (Fisher's exact test, P = 0.004). Self-limiting hematoma occurred in one patient after use of the long sheath and was considered a minor complication. CONCLUSION Ureteral catheterization using a long sheath is feasible and effective when antegrade ureteral intervention using a short sheath fails. When using a long sheath, the technical success rate was higher when advancing the balloon catheter over the guidewire than when advancing the guidewire through tight stricture.

Case Report: Lifesaving Hemostasis With Resuscitative Endovascular Balloon Occlusion of the Aorta in a Patient With Cardiac Arrest Caused by Upper Gastrointestinal Hemorrhage. Front Med (Lausanne) 2021; 8:777421.

Abstract
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is performed to treat hemorrhagic shock, whose cause is located below the diaphragm. However, its use in patients with gastrointestinal hemorrhage is relatively rare. The 45-year-old man with a history of dilated cardiomyopathy had experienced epigastric discomfort and had an episode of presyncope. On his presentation, the patient's blood pressure was 82/64 mmHg, heart rate 140/min, and consciousness level GCS E4V5M6. Hemodynamics stabilized rapidly with a transfusion that was administered on an emergency basis, and a blood sample only showed mild anemia (Hb, 11.5 g/dL). The patient was admitted to investigating the presyncope episode, and the planned endoscopy was scheduled the following day. The patient had an episode of presyncope soon and was found in hemorrhagic shock resulting from a duodenal ulcer rapidly deteriorated to cardiac arrest. Although a spontaneous heartbeat was restored with cardiopulmonary resuscitation, the patient's hemodynamics were unstable despite the emergency blood transfusion administered by pumping. Consequently, a REBOA device was placed, resuscitation was continued, and hemostasis was achieved by vascular embolization for the gastroduodenal artery. The patient was subsequently discharged without complications. However, there is no established evidence regarding the REBOA use in upper gastrointestinal hemorrhage, and the investigations that have been reported have been limited. Further, one recent research suggests that appropriate patient selection and early use may improve survival in these life-threatening cases. As was seen in the present case, REBOA can effectively treat upper gastrointestinal hemorrhage by temporarily stabilizing hemodynamics and enabling a hemostatic procedure to be quickly performed during that time. This report also demonstrated the hemodynamics during the combination of intermittent and partial REBOA to avoid the complications of ischemic or reperfusion injury of the intestines or lower extremities.

Abstract
BACKGROUND Rotator cuff calcific tendinopathy (RCCT) is a very frequent and debilitating disease often treated with Ultrasound-guided percutaneous irrigation (UGPI) followed by physiotherapy. OBJECTIVE A multicenter observational clinical study was designed to assess the effects of physiotherapy after UGPI on the functional recovery of the shoulders of patients suffering from RCCT. METHOD One hundred sixty-six patients (mean age 50.7± 7.6 years), 121 women, with painful RCCT were treated with UGPI and assessed at the day of UGPI (T0), and at one (T1), 3 (T2) and 6 (T3) months after treatment by the Constant- Murley Score (CMS), Oxford Shoulder Scale (OSS) and Numerical Rating Scale (NRS). Patients were divided into 2 groups, Physiotherapy (PT+) and not Physiotherapy (PT-) according to the performance of the rehabilitation program based on personal decision. RESULTS A significant improvement at T1 in all outcomes in both groups and between T1 and T3 for NRS during movement and OSS was found, but not for NRS at rest and CMS. There was no difference between groups for all outcome measures. In 27,1% of patients symptoms recurred in an average of 13 ± 8 weeks. CONCLUSIONS Results suggest that post-UGPI not-standardized physiotherapy might not provide additional clinical benefits in short and medium term. Further studies could assess the effectiveness of physiotherapy performed after three months in patients with recurrence of pain.

Abstract
A nodular lesion at the lower left pulmonary lobe was detected in a 46 years old male during a preoperative chest X-Ray for appendicitis. To further characterise the nodule, a contrast enhanced computed tomography (CE-CT) was performed showing a 20 mm vascular lesion, which was suspected to be a pseudoaneurysm. The diagnostic angiography detected a flattening of the vascular wall with a voluminous pseudoaneurysm (PSA) in the distal portion of the tributary branch of the inferior left lobe. To treat the lesion, a 2.9F microcatheter was advanced into the sac and 4 detachable coils were placed (16-18mm Penumbra Inc) to pack the PSA. To block vascular supply to the lesion, the feeding artery was embolized with an ethylene vinyl alcohol copolymer agent (Squid Peri 18, Emboflu). The final angiographic control showed the exclusion of the pseudoaneurysmal sac which was confirmed by SEMAR™ reconstructed CE-CT scan after 40 days. Furthermore, no signs of pulmonary infarction were reported. (www.actabiomedica.it).

Abstract
BACKGROUND Tumor response and survival varies in patients treated with transarterial chemoembolization (TACE) for intermediate stage hepatocellular carcinoma (HCC) and may be associated with several factors. PURPOSE To evaluate safety and efficacy of TACE in patients with intermediate stage HCC and to identify factors related to tumor response and survival. MATERIAL AND METHODS Consecutive patients with HCC treated with TACE between September 2008 and September 2018 were retrospectively reviewed. RESULTS In 87 patients (71 men; mean age = 68 ± 9 years), 327 TACE treatments were performed (mean = 3/patient; range = 1-12). Mean and median overall survival were 32 and 19 months, respectively. Survival rates at 30 days, one, three, and five years were 99%, 71%, 19%, and 8%, respectively. Objective response (OR) was seen in 84% and disease control (DC) was seen in 92% of the patients. Patients in whom peritumoral portal lipiodol enhancement (PPLE) was seen during TACE had better OR (97 vs. 73%; P = 0.007) and DC (100 vs. 85%; P = 0.024), and a reduced risk of death (hazard ratio [HR] = 0.52; 95% confidence interval = 0.32-0.86) compared to those without PPLE. Severe adverse events were rare (15%) and occurred more often in patients with a larger tumor size. CONCLUSIONS TACE was effective and safe in patients with intermediate stage HCC. Patients with PPLE during TACE had better tumor response and longer survival than those without PPLE. Severe adverse events occurred more often in patients with larger tumors.

Abstract
PURPOSE Real-time low latency MRI is performed to guide various cardiac interventions. Real-time acquisitions often require iterative image reconstruction strategies, which lead to long reconstruction times. In this study, we aim to reconstruct highly undersampled radial real-time data with low latency using deep learning. METHODS A 2D U-Net with convolutional long short-term memory layers is proposed to exploit spatial and preceding temporal information to reconstruct highly accelerated tiny golden radial data with low latency. The network was trained using a dataset of breath-hold CINE data (including 770 time series from 7 different orientations). Synthetic paired data were created by retrospectively undersampling the magnitude images, and the network was trained to recover the target images. In the spirit of interventional imaging, the network was trained and tested for varying acceleration rates and orientations. Data were prospectively acquired and reconstructed in real time in 1 healthy subject interactively and in 3 patients who underwent catheterization. Images were visually compared to sliding window and compressed sensing reconstructions and a conventional Cartesian real-time sequence. RESULTS The proposed network generalized well to different acceleration rates and unseen orientations for all considered metrics in simulated data (less than 4% reduction in structural similarity index compared to similar acceleration and orientation-specific networks). The proposed reconstruction was demonstrated interactively, successfully depicting catheters in vivo with low latency (39 ms, including 19 ms for deep artifact suppression) and an image quality comparing favorably to other reconstructions. CONCLUSION Deep artifact suppression was successfully demonstrated in the time-critical application of non-Cartesian real-time interventional cardiac MR.

Abstract
As a result of the increasing risk of developing radiation-related complications, many approaches aimed at reducing this risk and enhancing the outcomes of the patient, doctor or device operator have been developed. In this systematic review, we aim to discuss previous investigations that studied patient shielding or protection within the context of selected interventional radiology procedures. We included original studies that used Ka,r, and PKA for the assessment of the outcomes of two procedures: transjugular intrahepatic portosystemic shunt creation (TIPS) and hepatic arterial chemoembolization (HAE). A thorough search strategy was conducted on relevant databases to identify all relevant studies. We included 13 investigations, including 12 cross-sectional studies and one randomized controlled trial. Significant diversity was found among all these studies in terms of the used modalities, which made them hard to compare. However, almost all studies agreed that using novel imaging and interventional modalities is useful when obtaining better outcomes and reducing patient radiation exposure. The use of ultrasound-guided procedures and providing adequate lead curtains has also been recommended by the identified studies in order to minimize the frequency of radiation exposure. The reported Ka,r, and PKA were also variable between studies and were discussed within this study. Our findings indicate that unified guidelines for patient radiation shielding should be urgently investigated.
