Is the Internet a Suitable Patient Resource for Information on Common Radiological Investigations?: Radiology-Related Information on the Internet.

Rationale And Objective: This study aimed to assess the quality of Internet information about common radiological investigations.

Materials And Methods: Four search engines (Google, Bing, Yahoo, and Duckduckgo) were searched using the terms "X-ray," "cat scan," "MRI," "ultrasound," and "pet scan." The first 10 webpage results returned for each search term were recorded, and their quality and readability were analyzed by two independent reviewers (DJB and LCY), with discrepancies resolved by consensus.

Abdominal pain: a presentation of a vena cava aplasia complicated by thrombosis.

This case report describes a young man presenting with iliac fossa pain secondary to iliac vein thrombus due to inferior vena cava aplasia. No other identifiable risk factor or cause for deep vein thrombosis was demonstrated.

Dynamic MRI contrast enhancement of renal cortex: a functional assessment of renovascular disease in patients with renal artery stenosis.

Purpose: To evaluate differences in the magnitude and time course of renal cortical contrast uptake in patients with minimal, moderate, and severe renal artery stenosis (RAS) using contrast-enhanced magnetic resonance renography (CE-MRR).

Materials And Methods: CE-MRR was performed on 56 patients with renovascular disease using a three-dimensional volume interpolated breath-hold examination (VIBE) perfusion sequence. After administration of 2 mL of contrast, nine sequential axial VIBE datasets were acquired: at baseline, 7, 14, 21, 45, 60, 120, 180, and 240 seconds.

Two-dimensional flow quantitative MRI of aortic arch blood flow patterns: Effect of age, sex, and presence of carotid atheromatous disease on prevalence of spiral blood flow.

Purpose: To determine the effect of age, sex, and presence of carotid atheromatous disease on the presence of aortic spiral blood flow pattern using two-dimensional flow quantitative magnetic resonance imaging (MRI).

Materials And Methods: Sixty subjects (37 women, 23 men) were examined. Prospective phase contrast flow quantitative MRI (1.
