“…Our reporting of CAD-RADS categories and modifiers showed excellent IRA (ICC = 0.9862 and 0.8064, respectively). These results are very similar to that of the previous two studies [23,24], which assessed the interobserver agreement of CAD-RADS. However, as regards vulnerable plaque features (modifier "V"), the IRA was moderate (ICC = 0.5453).…”

Background: The coronary artery disease reporting and data system (CAD-RADS) is designed for a uniform standardization of coronary computed tomography angiography (CCTA) reporting and further management recommendations of coronary artery disease (CAD). This study aimed to assess clinical validity, applicability, and reproducibility of CAD-RADS in the management of patients with CAD. Methods and results:A single-center prospective study included 287 patients with clinically suspected or operated CAD who underwent CCTA. Four reviewers evaluated the CCTA images independently and assigned a CAD-RADS category to each patient. The invasive coronary angiography (ICA) was used as the reference standard for calculating diagnostic performance of CAD-RADS for categorizing the degree of coronary artery stenosis. The intra-class correlation (ICC) was used to test the inter-reviewer agreement (IRA). Reporting was provided to referring consultants according to the CAD-RADS. Based on ICA results, we have 156 patients with non-significant CAD and 131 patients with significant CAD. On a patient-based analysis, regarding those patients classified as CAD-RADS 4 and CAD-RADS 5 for predicting significant CAD, the CAD-RADS had a sensitivity, specificity, and an accuracy of 100%, 96.8 to 98.7%, and 98.3 to 99.3%, respectively, depending on the reviewer. There was an excellent IRA for CAD-RADS categories (ICC = 0.9862). The best cutoff value for predicting significant CAD was > CAD-RADS 3. Eightyseven percentage of referring consultants considered CAD-RADS reporting system to be "quite helpful" or "completely helpful" for clinical decision-making in CAD.Conclusion: CAD-RADS is valuable for improving CCTA structural reports and facilitating decision-making with high diagnostic accuracy and high reproducibility.

“…Second; this study applied CT for standardized reporting of acute appendicitis. Further studies using routine and diffusion MR imaging and comparing with CT for standardized reporting system of acute appendicitis are recommended (38)(39)(40). Outer to outer diameter of appendix: (a) axial CT scan shows distended appendix with outer to outer diameter less than 10mm (arrow).…”

Aim: To assess reliability of standardized reporting system of acute appendicitis at low-dose 320-rows CT. Methods: Retrospective analysis CT of 78 patients with pathologically proven acute appendicitis. The study was performed at low-dose 320-rows CT. The image analysis was performed by 2 radiologists according to standardized reporting system of acute appendicitis. Results: There was excellent overall of inter-observer agreement of both observers for standardized reporting system of acute appendicitis ( K = 0.89, 95% CI = 0.87-0.92, P = 0.001). There was good inter-observer agreement for visualization of appendix (K = 0.78, P = 0.001), tip diameter ( K = 0.75, P = 0.001), and single wall thickness of appendix ( K =0.77, P = 0.001). There was excellent inter-observer agreement for outer to outer wall diameter ( K = 0.82 , P = 0.001), mucosal hyper-enhancement ( K =0.80, P = 0.001), appendicolith ( K = 0.86, P = 0.001), gas in appendix ( K = 0.82, P = 0.001), surrounding fat stranding ( K = 0.81, P = 0.001), focal cecal thickening ( K = 0.85, P = 0.001), peri-appendiceal air ( K = 0.87, P = 0.001), peri-appendicular fluid collection, phlegmon, or abscess ( K = 0.82, P = 0.001), and right ovary cyst ( K = 0.83, P = 0.001). Conclusion: we concluded that excellent reliability of standardized reporting system of acute appendicitis in adults using low-dose 320-rows CT.

“…Several authors have emphasized the importance of early screening in patients with diabetes mellitus (T2DM) [15][16][17][18][54][55][56][57][58]. Patients with an eGFR below 60 mL/min/1.73 m 2 (stages 3-5 CKD) are at increased risk of CVD in comparison to the general population [11].…”

“…Where identifying CVD risk is concerned, different reporting systems in medical imaging have introduced uniform documenting linked with information controlling patient care (Abdel et al 2018). The Coronary Artery Disease Reporting and Data System (CAD-RADS TM) is a classification system suggested by the Society of Cardiovascular Computed Tomography, which has been used to establish coronary artery stenosis severity [57].…”

Cardiology and Nephrology specialties share several elements in the prevention of Cardiovascular Disease (CVD). CVD prevention in patients with CKD (Chronic Kidney Disease) can only really be understood if there are more robust collaborative clinical trials, and social sciences health research between nephrology and cardiology, not only to inform healthcare and best practices, but also to inform healthcare innovation. More than 80% of renal patients have one or more cardiovascular risk factors. Randomized Controlled Trials (RCTs) and social science research informs that compromised cardiac health is a key source of demise in patients. The aim here is to highlight the need for more robust collaborations between Nephrology, Cardiology and Therapeutic clinical trials, to preclude CVD complications in renal patients. Chemokine receptors are expressed on cell populations, permitting different chemokine to have selective activity. Chemokine are primarily involved in attraction of leukocytes. CVD intervention takes many forms but begins at acknowledging a need for more targeted therapeutics. Haemodialysis aggravates patient prognosis and myocardial function. Health awareness and education is still a much-needed resource for renal patients; more awareness and comprehension of CVD implemented as part of a patient's health plan. Now more than ever there needs to be a closer link between clinical trials between the two medical specialties, and social sciences to inform how best to prevent patients with CKD developing CVD events.
