Coronary computed tomography angiography (CTA) is becoming a popular non-invasive imaging modality for coronary arteries. It has high sensitivity and specificity in the evaluation of coronary artery disease (CAD). Due to its high negative predictive value, the main clinical role of coronary CTA is in the exclusion of significant CAD in the low to intermediate pretest probability patients. In the emergency department, coronary CTA helps to fast-track the triage of acute chest pain patients. One of the major coronary CTA's limitations is its false positive findings in the presence of heavily calcified lesions. With the advance of CT technology, the radiation dose of coronary CTA has been reduced significantly. At present, coronary CTA is still not indicated for screening asymptomatic patients.

Carotid body tumors (CBTs), rare neuroendocrine neoplasms near the carotid bifurcation, are mostly asymptomatic but may cause discomfort and autonomic dysfunction. Computed tomography angiography (CTA) is used for diagnosis, eliminating the need for a biopsy to avoid the risk of hemorrhage. Surgical excision is the preferred treatment, while radiotherapy is an option when surgery is impractical.

Introduction: Large artery atherosclerosis is a relevant cause of ischemic stroke. Beyond carotid artery stenosis ≥ 50%, causative in etiological classification of stroke, non-stenosing plaques are an increasingly reported cause of stroke with embolic pattern.
Methods: We are presenting the case of a 56 years old woman presenting with a first symptomatic multifocal ischemic stroke in the right internal carotid artery (ICA) territory on 2018 and a finding of asymptomatic past vascular injury in the same vascular territory on neuroimaging studies.

Deep femoral artery aneurysms are very rare; particularly when isolated and occur simultaneously in both limbs. We report such a case of a misdiagnosed 16-year-old male presenting after hematoma evacuation was attempted for painful swelling in the left groin. Once the diagnosis was confirmed by computed tomography angiography (CTA), an emergency aneurysmectomy with deep femoral artery (DFA) ligation was performed on the left limb.

Objectives: Screening for obstructive coronary artery disease (CAD) with coronary computed tomography angiography (CCTA) could prevent unnecessary invasive coronary angiography (ICA) procedures during work-up for trans-catheter aortic valve implantation (TAVI). CT-derived fractional flow reserve (CT-FFR) improves CCTA accuracy in chest pain patients. However, its reliability in the TAVI population is unknown.

Background: Despite advancements in valve implantation devices, vascular access complications (VAC) remain a significant cause of morbidity and mortality for those undergoing transcatheter aortic valve replacement (TAVR). We describe pre-operative imaging analysis of the aortoiliac and femoral arterial beds using the TransAtlantic intersociety consensus (TASC) score, ilio-femoral tortuosity, and procedural characteristics to identify anatomic risk factors predictive of VAC in TAVR.
Methods: Consecutive patients undergoing TAVR from 2012 to 2022 at a single North Dakota hospital were retrospectively reviewed.
