Acute hepatitis A: correlation of CT findings with clinical phase.

Background/aims: The purpose of this study was to evaluate the incidences of various multi-detector CT (MDCT) findings in acute viral hepatitis A (AHA) and to determine if there are associations between these CT findings and the clinical phases of AHA.

Methodology: Eighty-five patients with AHA were enrolled in this study. The patients were divided into three groups according to changes in their serum alanine aminotransferase and bilirubin levels before and after performing MDCT: group 1 (n = 16, prodromal phase); group 2 (n = 41, jaundice phase); group 3 (n = 28, recovery phase).

Current Concepts in Cardiac CT Angiography for Patients With Acute Chest Pain.

This article presents specific examples of delayed diagnosis of acute coronary syndrome, acute aortic dissection, and pulmonary embolism resulting from evaluating patients with nonspecific acute chest pain who did not undergo immediate dedicated coronary CT angiography (CTA) or triple rule-out protocol (TRO). These concrete examples of delayed diagnosis may advance the concept of using cardiac CTA (i.e.

MDCT evaluation of acute aortic syndrome.

MDCT plays an important role in the rapid and accurate diagnosis of AAS. Precise understanding of the current concepts and various CT features of subtypes of AAS is helpful in diagnosing AAS and improving patient outcome.

MDCT evaluation of acute aortic syndrome.

This article provides a summary of acute aortic syndrome (AAS), focusing especially on the multidetector CT technique and findings of AAS, as well as recent concepts regarding the subtypes of AAS, consisting of aortic dissection, intramural hematoma, penetrating atherosclerotic ulcer, and unstable aortic aneurysm.
