Mumtaz ZUA, Desai SR, Padley SPG. Frequency of extracardiac findings on "negative" CT coronary angiography studies. Clin Radiol 2024; 79:e334-e343. [PMID: 38092649 DOI: 10.1016/j.crad.2023.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 11/01/2023] [Accepted: 11/02/2023] [Indexed: 01/02/2024]
Abstract
AIM To evaluate the prevalence and nature of extracardiac findings identified on computed tomography (CT) coronary angiography (CTCA) in patients with chest pain but without evidence of coronary artery disease (CAD). MATERIALS AND METHODS CTCA studies in patients referred to the hospital between January 2017 to February 2021 with chest pain and a suspected diagnosis of CAD were reviewed retrospectively for the presence of extracardiac findings. Consensus review of CTCA studies was performed by two experienced thoracic radiologists. The presence and severity of extracardiac findings, together with the likelihood that chest pain might be attributed to these, was recorded. Patient records were reviewed to ascertain the recording of extracardiac findings on initial CTCA reports and, where applicable, the nature of the follow-up. RESULTS Extracardiac findings (n=210) were present in 110/180 patients (61%) with a mean of 1.9 findings per patient. Extracardiac findings were more prevalent in patients aged ≥65 years compared to those <65 years (p<0.001). At least one extracardiac finding with the potential to cause chest pain was present in 40 patients (22%): degenerative disc disease (n=23 [13%]) and hiatus hernia (n=6 [3.3%]) were the most common extracardiac findings. Only 37.6% (79) of all retrospectively identified findings had been initially reported and, of these, 12.7% (10) required further follow-up. CONCLUSION Extracardiac findings are common in patients with no evidence of CAD on CTCA. The entire dataset should be evaluated for the presence of extracardiac findings that could explain chest pain symptoms on wide field of view reconstructions.

Detection of relevant extracardiac findings on coronary computed tomography angiography vs. invasive coronary angiography. Eur Radiol 2021; 32:122-131. [PMID: 34129067 PMCID: PMC8660731 DOI: 10.1007/s00330-021-07967-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 03/11/2021] [Accepted: 03/31/2021] [Indexed: 12/21/2022]
Abstract
OBJECTIVES To compare the detection of relevant extracardiac findings (ECFs) on coronary computed tomography angiography (CTA) and invasive coronary angiography (ICA) and evaluate the potential clinical benefit of their detection. METHODS This is the prespecified subanalysis of ECFs in patients presenting with a clinical indication for ICA based on atypical angina and suspected coronary artery disease (CAD) included in the prospective single-center randomized controlled Coronary Artery Disease Management (CAD-Man) study. ECFs requiring immediate therapy and/or further workup including additional imaging were defined as clinically relevant. We evaluated the scope of ECFs in 329 patients and analyzed the potential clinical benefit of their detection. RESULTS ECFs were detected in 107 of 329 patients (32.5%; CTA: 101/167, 60.5%; ICA: 6/162, 3.7%; p < .001). Fifty-nine patients had clinically relevant ECFs (17.9%; CTA: 55/167, 32.9%; ICA: 4/162, 2.5%; p < .001). In the CTA group, ECFs potentially explained atypical chest pain in 13 of 101 patients with ECFs (12.9%). After initiation of therapy, chest pain improved in 4 (4.0%) and resolved in 7 patients (6.9%). Follow-up imaging was recommended in 33 (10.0%; CTA: 30/167, 18.0%; ICA: 3/162, 1.9%) and additional clinic consultation in 26 patients (7.9%; CTA: 25/167, 15.0%; ICA: 1/162, 0.6%). Malignancy was newly diagnosed in one patient (0.3%; CTA: 1/167, 0.6%; ICA: 0). CONCLUSIONS In this randomized study, CTA but not ICA detected clinically relevant ECFs that may point to possible other causes of chest pain in patients without CAD. Thus, CTA might preclude the need for ICA in those patients. TRIAL REGISTRATION NCT Unique ID: 00844220 KEY POINTS: • CTA detects ten times more clinically relevant ECFs than ICA. • Actionable clinically relevant ECFs affect patient management and therapy and may thus improve chest pain. • Detection of ECFs explaining chest pain on CTA might preclude the need for performing ICA.

Clin Anat 2021; 34:872-883. [PMID: 33908686 DOI: 10.1002/ca.23737] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Revised: 02/22/2021] [Accepted: 03/11/2021] [Indexed: 12/15/2022]
Abstract
The azygos lobe (AL) is an accessory lobe of the right lung with prevalence between 0.4 and 1.2%. The aim of the present review is to provide a better estimate of the frequency of the AL and to examine its relationships with other variables such as population, diagnostic methods, and co-occurring illnesses. Studies published between 1899 and October 2020 were searched through three electronic databases; Google Scholar, PubMed, and JSTOR. Titles, abstracts, and full texts of the retrieved entries were screened to determine their appropriateness for inclusion. A total of 88 studies relating to 1,033,083 subjects met the inclusion criteria. A random-effects meta-analysis yielded an overall prevalence of 0.30% (95% CI: 0.0024-0.0035, I2 = 97.9%). Linear regression and subgroup analysis revealed a negative correlation (ρ = -0.540, p <0.001) between AL prevalence and sample size; studies with smaller sample sizes had higher prevalences. The AL prevalence in individuals with congenital pulmonary defects, 5.2% (95% CI: 0.0018-0.0086, I2 = 0%), was 17 times higher than the overall prevalence (z = 6.65, p <0.001), suggesting associations with other abnormalities and possibly a genetic predisposition. In addition to an evidence-based synthesis of AL prevalence, this study demonstrates publication bias and small-study effects in the anatomy literature. Awareness of the AL is crucial for radiologists when they interpret unusual radiological findings and for surgeons when they operate in the region.

Abstract
Coronary CT angiograms are commonly performed for the evaluation of coronary artery disease and coronary arterial anatomy. However, extracardiac findings are frequently detected on these examinations and often can explain patients’ underlying symptoms, having a significant impact on patient management. Here in, we discuss three cases of incidentally detected novel COVID-19-infected pneumonia (NCIP). This case series highlights the image findings in NCIP and emphasizes the importance of evaluating all organs in the field of view on coronary CT angiograms. In addition, with the ongoing outbreak of COVID-19 and exponentially increasing incidence throughout the world, this report stresses the need for including NCIP in the differential diagnosis of patients with typical image findings in at-risk populations, as early diagnosis is crucial for appropriate patient management and post-exposure recommendations.

Abstract
Objectives: The objectives of this study were to estimate the prevalence and significance of incidental non-cardiac findings (INCFs) in coronary computed tomography angiography (CCTA) using a dual-source multidetector computed tomography. Materials and Methods: Retrospective review of all CCTA studies performed over a time period for various indications was included in the study. After exclusions, CCTA of 1713 patients was evaluated by two experienced cardiac radiologists for non-cardiac abnormalities in the full field-of-view limited contrast chest series. The scans were acquired from the level of the carina to just below the diaphragm. INCFs were classified into three categories: Significant, indeterminate, and insignificant findings based on their clinical impact and availability of prior imaging and clinical details. Results: The study cohort consisted of 1123 males (mean age of 58 years) and 590 females (mean age of 64 years). INCFs were seen in 600 patients of 1713 patients. A total of 812 INCFs (47.5%) were found in 1713 patients. Of those, 568 (70%) were considered insignificant, 205 (25.2%) indeterminate, and 39 significant findings (4.9%). The prevalence of significant findings was 2.3%. Among the 39 significant findings, after correlating with clinical details and other imaging, nine were really significant findings (0.5%) and out of this, four turned out to be cancers (0.2%). Conclusion: Large number of INCFs can be found in CCTA with majority of them being insignificant or of minimal clinical impact. Although the proportion of significant findings is small and may not be cost beneficial, it is prudent to evaluate all the available data and to make appropriate classification of INCFs which can help in further management.

Abstract
Background The purpose of this study is to investigate the prevalence of a history of malignancy in patients with chest pain who were referred for computed tomography angiography as well as the long-term survival and cardiovascular outcomes, including coronary artery disease (CAD) and coronary artery calcium (CAC) percentiles of cancer survivors. These data are relevant since it is unknown how cancer survivors, who underwent cardio-toxic therapies, should be monitored. Methods We analysed all patients with chest pain, who came to the outpatient clinic and underwent computed tomography angiography. The primary study endpoint was long-term survival. The secondary endpoints included CAD on computed tomography angiogram (CTA), CAC percentiles, suspected and confirmed malignancy on CTA, and other accidental findings on CTA. Results Of all 1,892 patients included in the analyses, 133 (7%) had a history of malignancy and 1,759 (93%) did not. Mortality rates were higher for the cancer survivors (6.5% vs 20.9% after ten years, p < 0.001). The multivariable Cox regression model also showed higher mortality for cancer survivors after ten years (adjusted hazard ratio 2.48 [95% confidence interval: 1.58–3.90]). CAD did not differ between both groups. CAC percentiles were higher in cancer survivors (p = 0.037). Cancer survivors had more suspected malignancies (3.8% vs 0.5%; p = 0.001) and also more confirmed malignancies on CTA (3.0% vs 0.1%; p < 0.001). Conclusions Cancer survivors have higher mortality rates, no difference in CAD on CTA, higher CAC percentiles and more often malignancy on CTA compared with patients without a cancer history.

Abstract
Enhanced computed tomography (CT) is widely used for evaluating acute biliary pain in the emergency department (ED). However, concern about radiation exposure from CT has also increased. We investigated the usefulness of pre-contrast CT for differential diagnosis in middle-aged subjects with suspected biliary pain.A total of 183 subjects, who visited the ED for suspected biliary pain from January 2011 to December 2012, were included. Retrospectively, pre-contrast phase and multiphase CT findings were reviewed and the detection rate of findings suggesting disease requiring significant treatment by noncontrast CT (NCCT) was compared with cases detected by multiphase CT.Approximately 70% of total subjects had a significant condition, including 1 case of gallbladder cancer and 126 (68.8%) cases requiring intervention (122 biliary stone-related diseases, 3 liver abscesses, and 1 liver hemangioma). The rate of overlooking malignancy without contrast enhancement was calculated to be 0% to 1.5%. Biliary stones and liver space-occupying lesions were found equally on NCCT and multiphase CT. Calculated probable rates of overlooking acute cholecystitis and biliary obstruction were maximally 6.8% and 4.2% respectively. Incidental significant finding unrelated with pain consisted of 1 case of adrenal incidentaloma, which was also observed in NCCT.NCCT might be sufficient to detect life-threatening or significant disease requiring early treatment in young adults with biliary pain.

Abstract
OBJECTIVES To study associations between chest HRCT signs and subsequent deaths in long-term follow-up. METHODS Lung and pleural signs of 633 asbestos exposed workers (age 45-86, mean 65) screened with HRCT were recorded by using the International Classification of Occupational and Environmental Respiratory Diseases (ICOERD) system, which contains detailed instructions for use and reference images. Subsequent mortality was checked from the national register. Cox regression adjusted for covariates (age, sex, BMI, asbestos exposure, pack-years) was used to explore the relations between HRCT signs and all-cause deaths, cardiovascular and benign respiratory deaths, and deaths from neoplasms - all according to the ICD-10 diagnostic system. RESULTS The follow-up totalled 5271.9 person-years (mean 8.3 y/person, range .04-10.3). 119 deaths were reported. Irregular/linear opacities, honeycombing, emphysema, large opacities, visceral pleural abnormalities and bronchial wall thickening were all significantly related to all-cause deaths. Most of these signs were associated also with deaths from neoplasms and benign respiratory disease. Deaths from cardiovascular disease were predicted by emphysema and visceral pleural abnormalities. CONCLUSIONS Several HRCT signs predicted deaths. Careful attention should be paid on subjects with radiological signs predictive of deaths and new secondary preventive strategies developed. This calls for further focused studies among different populations.

Abstract
OBJECTIVE The purpose of this study was to determine the prevalence and clinical importance of incidental findings of noncoronary cardiac structures and mediastinal great vessels in patients who underwent coronary computed tomography angiography (CCTA). METHODS The study included 2,096 consecutive patients (1,472 men and 624 women, with a mean age of 55 years). Cardiovascular findings were categorized into three groups according to the clinical importance: group 1 included findings necessitating immediate treatment or intervention; group 2 included findings requiring clinical awareness, follow-up, or further clinical and/or radiological investigations; and group 3 included findings not requiring any follow-up or further tests. We also evaluated whether there was any previous diagnosis of cardiovascular findings. RESULTS A total of 174 abnormalities (8.3 %) were detected in 170 patients. Of these abnormalities, 21 findings (12 %) were considered as group 1, 121 (69.5 %) as group 2, and 32 (18.5 %) as group 3. The majority of cardiovascular findings (140 of 174, 80.5 %) were unknown by the reporter during the interpretation of CCTA examinations and regarded as incidental findings. CONCLUSION Noncoronary incidental cardiovascular findings in patients who underwent CCTA are common. It is important to be aware of these findings necessitating immediate treatment or intervention, and follow-up or further investigations, and careful attention must be paid to all the structures included in the images.

Abstract
The cardiac structures are well seen on nongated thoracic computed tomography studies in the investigation and follow-up of cardiopulmonary disease. A wide variety of findings can be incidentally picked up on careful evaluation of the pericardium, cardiac chambers, valves, and great vessels. Some of these findings may represent benign variants, whereas others may have more profound clinical importance. Furthermore, the expansion of interventional and surgical practice has led to the development and placement of new cardiac stents, implantable pacemaker devices, and prosthetic valves with which the practicing radiologist should be familiar. We present a collection of common incidental cardiac findings that can be readily identified on thoracic computed tomography studies and briefly discuss their clinical relevance.

Abstract
Objectives To determine the prevalence of clinically relevant unrequested extra-cardiac imaging findings on cardiac Computed Tomography (CT) and explanatory factors thereof. Methods A systematic review of studies drawn from online electronic databases followed by meta-analysis with meta-regression was performed. The prevalence of clinically relevant unrequested findings and potentially explanatory variables were extracted (proportion of smokers, mean age of patients, use of full FOV, proportion of men, years since publication). Results Nineteen radiological studies comprising 12922 patients met the inclusion criteria. The pooled prevalence of clinically relevant unrequested findings was 13% (95% confidence interval 9–18, range: 3–39%). The large differences in prevalence observed were not explained by the predefined (potentially explanatory) variables. Conclusions Clinically relevant extra-cardiac findings are common in patients undergoing routine cardiac CT, and their prevalence differs substantially between studies. These differences may be due to unreported factors such as different definitions of clinical relevance and differences between populations. We present suggestions for basic reporting which may improve the interpretability and comparability of future research.

Abstract
Background Investigation of pulmonary pathology with computed tomography also allows visualisation of the heart and major vessels. We sought to explore whether clinically relevant cardiac pathology could be identified on computed tomography pulmonary angiograms (CTPA) requested for the exclusion of pulmonary embolism (PE). 100 consecutive CT contrast-enhanced pulmonary angiograms carried out for exclusion of PE at a single centre were assessed retrospectively by two cardiologists. Findings Evidence of PE was reported in 5% of scans. Incidental cardiac findings included: aortic wall calcification (54%), coronary calcification (46%), cardiomegaly (41%), atrial dilatation (18%), mitral annulus calcification (15%), right ventricular dilatation (11%), aortic dilatation (8%) and right ventricular thrombus (1%). Apart from 3 (3%) reports describing cardiomegaly, no other cardiac findings were described in radiologists' reports. Other reported pulmonary abnormalities included: lung nodules (14%), lobar collapse/consolidation (8%), pleural effusion (2%), lobar collapse/consolidation (8%), emphysema (6%) and pleural calcification (4%). Conclusions CTPAs requested for the exclusion of PE have a high yield of cardiac abnormalities. Although these abnormalities may not have implications for acute clinical management, they may, nevertheless, be important in long-term care.

Incidental non-cardiac findings of a coronary angiography with a 128-slice multi-detector CT scanner: should we only concentrate on the heart? Korean J Radiol 2009; 11:60-8. [PMID: 20046496 PMCID: PMC2799652 DOI: 10.3348/kjr.2010.11.1.60] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2009] [Accepted: 07/28/2009] [Indexed: 12/15/2022] Open
Abstract
Objective To evaluate the spectrum, prevalence, and significance of incidental non-cardiac findings (INCF) in patients referred for a non-invasive coronary angiography using a 128-slice multi-detector CT (MDCT). Materials and Methods The study subjects included 1,044 patients; 774 males (mean age, 59.9 years) and 270 females (mean age, 63 years), referred for a coronary CT angiography on a 128-slice MDCT scanner. The scans were acquired from the level of the carina to just below the diaphragm. To evaluate INCFs, images were reconstructed with a large field of view (> 300 mm) covering the entire thorax. Images were reviewed in the axial, coronal, and sagittal planes, using the mediastinal, lung, and bone windows. The INCFs were classified as severe, indeterminate, and mild, based on their clinical importance, and as thoracic or abdominal based on their locations. Results Incidental non-cardiac findings were detected in 56% of patients (588 of 1,044), including 435 males (mean age, 65.6 years) and 153 females (mean age, 67.9 years). A total of 729 INCFs were observed: 459 (63%) mild (58% thoracic, 43% abdominal), 96 (13%) indeterminate (95% thoracic, 5% abdominal), and 174 (24%) severe (87% thoracic, 13% abdominal). The prevalence of severe INCFs was 15%. Two severe INCFs were histologically verified as lung cancers. Conclusion The 128-slice MDCT coronary angiography, in addition to cardiac imaging, can provide important information on the pathology of the chest and upper abdomen. The presence of severe INCFs is not rare, especially in the thorax. Therefore, all organs in the scan should be thoroughly evaluated in daily clinical practice.
