Abstract
Objective: This study aimed to observe the preventive effect of prophylactic treatment on joint health in people with hemophilia (PwH) and to investigate the importance of integration of ultrasonographic examination into clinical and radiological evaluation of the joints. Materials and Methods: This national, multicenter, prospective, observational study included male patients aged ≥6 years with the diagnosis of moderate or severe hemophilia A or B from 8 centers across Turkey between January 2017 and March 2019. Patients were followed for 1 year with 5 visits (baseline and 3rd, 6th, 9th, and 12th month visits). The Hemophilia Joint Health Score (HJHS) was used for physical examination of joints, the Pettersson scoring system was used for radiological assessment, point-of-care (POC) ultrasonography was used for bilateral examinations of joints, and the Hemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) score was used for evaluation of ultrasonography results. Results: Seventy-three PwH, of whom 62 had hemophilia A and 11 had hemophilia B, were included and 24.7% had target joints at baseline. The HJHS and HEAD-US scores were significantly increased at the 12th month in all patients. These scores were also higher in the hemophilia A subgroup than the hemophilia B subgroup. However, in the childhood group, the increment of scores was not significant. The HEAD-US total score was significantly correlated with both the HJHS total score and Pettersson total score at baseline and at the 12th month. Conclusion: The HEAD-US and HJHS scoring systems are valuable tools during follow-up examinations of PwH and they complement each other. We suggest that POC ultrasonographic evaluation and the HEAD-US scoring system may be integrated into differential diagnosis of bleeding and long-term monitoring for joint health as a routine procedure.

Abstract
PURPOSE We aimed to determine the feasibility and effectiveness of agent emission imaging - high mechanical index (AEI-High MI) mode ultrasonography (US) compared with gray-scale and color Doppler US, alone or in combination, for the diagnosis of urolithiasis with reference to unenhanced computed tomography (CT). METHODS This prospective study included 72 consecutive patients (40 males, 32 females; mean age, 45.9±14.7 years) referred by the department of urology for acute or elective symptoms of urolithiasis and confirmed to have urinary calculi on unenhanced abdominal CT, between January 2015 and June 2015. Gray-scale, color Doppler, and AEI-High MI US were performed by two radiologists to determine the effectiveness of these methods in the diagnosis of urinary stones and to compare them with the reference modality. RESULTS A total of 189 calculi were detected on CT examination. Gray-scale US had a sensitivity of 66.1% and positive predictive value (PPV) of 88.7% for detecting calculi, while twinkling artifact of color Doppler had a sensitivity of 70.4% and PPV of 94.3%. The scintillation artifact of AEI-High MI mode had a sensitivity of 75.1% and PPV of 95.9%. When all ultrasound-based modalities were combined, the sensitivity and PPV rose to 83.1% and 88.2%, respectively. When calculi were grouped according to their size ( < 5 mm, 5-10 mm, > 10 mm), AEI-High MI mode had a higher sensitivity (60%) compared with gray-scale (32.5%) and color Doppler (41.3%) for calculi < 5 mm. CONCLUSION AEI-High MI mode had a higher sensitivity compared with gray-scale and color Doppler for the detection of calculi smaller than 5 mm, but it did not make a significant contribution to detection of larger calculi. The combined use of gray-scale US with AEI-High MI mode could increase the detection rate of calculi smaller than 5 mm and provide a method for verification of suspected calculi on gray-scale US.

Abstract
Alveolar echinococcosis is a parasitic disease limited to the northern hemisphere. The disease occurs primarily in the liver and shows a profile mimicking slow-growing malignant tumors. Echinococcus multilocularis infection is fatal if left untreated. It can cause several complications by infiltrating the vascular structures, biliary tracts, and the hilum of the liver. As it can invade the adjacent organs or can spread to distant organs, alveolar echinococcosis can easily be confused with malignancies. We provide a brief review of epidemiologic and pathophysiologic profile of alveolar echinococcosis and clinical features of the disease. This article focuses primarily on the imaging features of alveolar echinococcosis on ultrasonogra-phy, computed tomography, magnetic resonance imaging, diffusion-weighted imaging and positron emission tomography-computed tomography. We also reviewed the role of radiology in diagnosis, management, and follow-up of the disease.

Abstract
BACKGROUND Renal aspergillosis is a rare infection that usually occurs in persons with a predisposition for this condition. Its differential diagnosis includes primary and metastatic renal malignancies, pyelonephritis and secondary abscess formation, granulomatous disorders, and renal infarction. We aim to stress the role of multimodality imaging and percutaneous biopsy in the diagnosis of this condition. CASE REPORT We present diffusion weighted imaging (DWI) and positron emission tomography-computed tomography (PET-CT) findings in addition to conventional imaging modalities in a 55-year-old man with secondary renal aspergilloma. CONCLUSION Radiological imaging methods are an integral part of diagnostic workup for renal aspergillosis. A definitive diagnosis is made by histopathological and/or microbiological examination of the material obtained via percutaneous biopsy under guidance of imaging methods.

Abstract
INTRODUCTION Hemangiomas are the most common benign lesions of the liver. They usually remain asymptomatic and it is sufficient to follow up with intermittent imaging methods. The case presented herein featured with localization and atypical symptoms. PRESENTATION OF CASE A man aged 59 years was admitted with a three-month history of continuous and recently increased abdominal pain, and also early satiety. Computed Tomography (CT) showed a 9×6-cm mass that compressed the spleen on the left sub-diaphragmatic area, attached to the inferior part of the diaphragm. The mass was removed laparoscopically and pathology was cavernous hemangioma. DISCUSSION Although surgical treatment of cavernous hemangioma of the liver (CHL) remains in the background, for symptomatic patients who have no clear diagnosis, when complications emerge, surgery can be preferable. Here in minimally invasive surgery was performed in this case suffering from atypical abdominal pain. CONCLUSION Cavernous hemangiomas of the liver rarely require treatment. Surgery is one of the options in selected cases and abdominal pain is one of the indications. In patients complaining from persistent abdominal pain, if intraabdominal atypical-localized mass was seen in examinations, hemangioma should be remembered in differential diagnosis.

Abstract
BACKGROUND Early detection of coronary artery disease (CAD) is important because of the high morbidity and mortality rates. As invasive coronary angiography (ICA) is an invasive procedure, an alternative diagnostic method; coronary computed tomography angiography (CTA), has become more widely used by the improvements in detector technology. AIMS In this study, we aimed to examine the accuracy and image quality of high-pitch 128-slice dual-source CTA taking the ICA as reference technique. We also aimed to compare the accuracy and image quality between different heart rate groups of >70 beates per minute (bpm) and ≤70 bpm. STUDY DESIGN Retrospective cross-sectional study. METHODS Among 450 patients who underwent coronary CTA with the FLASH spiral technique, performed with a second generation dual-source computed tomography device with a pitch value of 3.2, 102 patients without stent and/or bypass surgery history and clinically suspected coronary artery disease who underwent ICA within 15 days were enrolled. Image quality was assessed by two independent radiologists using a 4-point scale (1=absence of any artifacts- 4=non-evaluable). A stenosis >50% was considered significant on a per-segment, per-vessel, and per-patient basis and ICA was considered the reference method. Radiation doses were determined using dose length product (DLP) values detected by the computed tomography (CT) device. In addition, patients were classified into two groups according to their heart rates as ≤70 bpm (73 patients) and >70 bpm (29 patients). The relation between the diagnostic accuracy and heart rate groups were evaluated. RESULTS Overall, 1495 (98%) coronary segments were diagnostic in 102 patients (32 male, 70 female, mean heart rate: 65 bpm). There was a significant correlation between image quality and mean heart rate in the right coronary artery (RCA) segments. The effective radiation dose was 0.98±0.09 mili Sievert (mSv). On a per-patient basis, sensitivity, specificity, and positive and negative predictive values were 93.8%, 88.8%, 93.8% and 88.8%, respectively. These values were also similar in per-vessel and per-segment basis. Two different groups categorized by mean heart rate had almost similar results in terms of the diagnostic power of dual-source CTA. CONCLUSION CTA with a high pitch value is a reliable, non-invasive diagnostic method that can CAD with low radiation doses not only in patients with a heart rate below 70 bpm, but also in patients with higher heart rates.

Abstract
BACKGROUND This study was designed to investigate the diagnostic efficacy of computed tomography (CT) for the detection diaphragmatic injury in cases undergoing diagnostic and therapeutic laparoscopy in left thoracoabdominal penetrating injuries. METHODS Demographic properties, stabbed body region, additional injuries, hemodynamic parameters, time to admission, diagnostic examinations, and type of treatment were retrospectively reviewed in one hundred and eight patients presenting with left thoracoabdominal injury after penetrating sharp object injury between April 2010 and December 2014. Preoperative CT scans of all patients were reviewed blind to the results of surgical evaluation. The relationship between diaphragmatic injury and hemothorax, pneumothorax, abdominal free fluid, and solid organ injuries were analyzed. All patients underwent physical examination, complete blood count monitoring, and hemodynamic assessment prior to surgery. RESULTS The most common finding on physical examination was anterior left thoracoabdominal injury. The injury was detected surgically in 36% of twenty-five cases with lateral injury. Diaphragmatic injury was present in twenty-five (23.1%) of all cases, all of whom were treated with laparoscopic repair. An analysis of all CT findings in relation to surgical results revealed that CT had a sensitivity of 80%, a specificity of 95%, a PPV of 83%, and a NPV of 94% for the detection of diaphragmatic injuries. Mean duration of hospital stay was 5.4 days (range, 1-16 days) in the entire study population. CONCLUSION CT is still associated with diagnostic challenges in penetrating diaphragmatic injuries. Nevertheless, CT showed a high specificity and a negative predictive value in our study. Detection of a diaphragmatic defect and fatty tissue herniation makes the definitive diagnosis of diaphragmatic injury in penetrating thoracoabdominal injuries. Prospective studies with a larger sample size are necessary to further clarify the role of CT in detection of diaphragmatic injuries in thoracoabdominal sharp penetrating object injuries.

Abstract
OBJECTIVE To investigate the role of density value in computed tomography (CT) and twinkling artifact observed in color Doppler analysis for the prediction of the mineral composition of urinary stones. MATERIAL AND METHODS A total of 42 patients who were operated via percutaneous or endoscopic means and had undergone abdominal non-contrast CT and color Doppler ultrasonography examinations were included in the study. X-ray diffraction method was utilized to analyze a total of 86 stones, and the correlations between calculated density values and twinkling intensities with stone types were investigated for each stone. RESULTS Analyses of extracted stones revealed the presence of 40 calcium oxalate monohydrate, 12 calcium oxalate dihydrate, 9 uric acid, 11 calcium phosphate, and 14 cystine stones. The density values were calculated as 1499±269 Hounsfield Units (HU) for calcium oxalate monohydrate, 1505±221 HU for calcium oxalate dihydrate, 348±67 HU for uric acid, 1106±219 HU for calcium phosphate, and 563±115 HU for cystine stones. The artifact intensities were determined as grade 0 in 15, grade 1 in 32, grade 2 in 24, and grade 3 in 15 stones. CONCLUSION In case the density value of the stone is measured below 780 HU and grade 3 artifact intensity is determined, it can be inferred that the mineral composition of the stone tends to be cystine.

Abstract
Foreign body ingestion is a common problem in children, but it is also seen among adults. Most foreign bodies pass through the gastrointestinal tract without causing complications. Perforation of the gut by a foreign body, followed by migration of the foreign body to the liver is quite rare. Herein we report a case of inadvertent ingestion of a sewing needle that perforated the duodenum and migrated to the liver. The patient was monitored weekly with abdominal radiographs, but displacement of the needle could not be observed. At follow-up, right upper quadrant pain was noted. Two weeks later, computed tomography revealed that the needle was completely buried into the right lobe of the liver. Ultrasonographic examination successfully showed the extracapsular displacement of the needle. Eventually, laparoscopic removal of the needle was easily performed.
