ConclusionCardiac high-pitch CTA of neonates with CHD can be performed safely and dose-reducing without additional test bolus or bolus tracking scan. With very good image quality, it provides a detailed insight into the cardiac anatomy and thus enables a differentiated, noninvasive therapy planning.

We present a case series in which 5 eyes of 3 patients with Eales disease were evaluated by using retinal fluorescein angiography with 30 º, 50º, and 150º lenses in a laser-scanning ophthalmoscope. These cases highlight the usefulness of wide-field fluorescein angiography in the diagnosis and follow-up of peripheral ischemic retinal areas in Eales disease, which enables better follow-up than possible with conventional fluorescein a ngiography images.RESUMO A angiografia de campo amplo permite avaliar áreas periféricas com melhor qualidade e proporciona maior foco profundo, melhorando a imagem d...

First description in the literature of incidental saddle pulmonary embolus diagnosed on18F ‐labelled fluoro‐2‐deoxyglucose positron emission tomography/computed tomography by seeing pulmonary infarction and right‐sided myocardial uptake. This will alert clinicians about the importance of these signs and direct emergent of further investigation and therapy. 18F ‐labelled fluoro‐2‐deoxyglucose positron emission tomography/computed tomography (18F ‐FDG PET/CT) is used extensively in the setting of cancer staging and in assessing cancer treatment response. Oncology patients have a sevenfold risk of developing p...

ConclusionsA panel of experts on the imaging of GI bleeding from the Society of Abdominal Radiology was able to reach consensus on the majority of technical parameters used for CTA of overt GI bleeding. These recommendations should improve the quality of patient care by adopting these minimal technical requirements for optimal exam performance and lead to less variation in the performance of these exams which will facilitate collecting and comparing published data from different centers. These recommendations will need revisions as additional scientific data become available.

A 17-month-old male child presented with cyanosis and failure to thrive. Transthoracic echocardiography suggested a diagnosis of tetralogy of Fallot (TOF). The mitral valve leaflets were thickened without any hemodynamic evidence of stenosis or regurgitation and a normal-sized left atrium (LA). Concentric left ventricular hypertrophy (LVH) was also noted. Patient was referred for a computed tomography angiography (CTA) for better characterization of the cardiac and extracardiac anomalies. The scan was performed on a SOMATOM FORCE (Siemens Healthcare, Forchheim, Germany) CT scanner which is a third-generation dual source CT...

A 24-year-old woman was admitted to our hospital after convulsive status epilepticus. A cerebral magnetic resonance venography revealed a persistent fetal falcine sinus. Additionally, the posterior third of the superior sagittal sinus was hypoplastic and the abnormal deep venous drainage was accompanied. These abnormalities had already been detected by magnetic resonance imaging several years ago. In the present scan, we discovered a sinus thrombosis in the hypoplastic superior sagittal sinus. In the cerebral angiography, we observed delayed venous return in the left parieto-occipital lobe and hypothesized that cerebral ve...

AbstractThe purpose of the study was to evaluate the optimal cut-off value of CT-Fractional Flow Reserve (CT-FFR) using fluid –structure interaction and how to adjust the CT-FFR’s underestimation from a standpoint of minimize 1-year cardiac events. Subjects were 38 cases with 44 vessels in which stenosis of 30–90% was detected using one-rotation scanning by 320-row coronary CT angiography (CCTA) and invasive FFR (i-F FR) was performed within subsequent 90 days. CT-FFR was calculated using on-site from the multiple cardiac phases. A hypothetical 1-year cardiac event incidence was estimated using previ...
