The Effect of Oral Laxatives on Rectal Distension and Image Quality in Magnetic Resonance Imaging of the Prostate.

Introduction Increasing rectal size is associated with increased artefacts on magnetic resonance imaging (MRI) of the prostate and has the potential to degrade image quality. The objective of this study was to analyse the effect of oral laxative medication on rectal distension and image quality in prostate MRI. Methods Eighty patients prospectively received either 15 mg of oral senna (laxative group) or no medication (control group).

Coronary artery calcification on routine CT has prognostic and treatment implications for all ages.

Aims: Guidelines have recommended reporting coronary artery calcification (CAC) if present on chest CT imaging regardless of indication. This study assessed CAC prevalence, prognosis and the potential clinical impact of its reporting.

Methods: We performed a single-centre retrospective analysis (January-December 2015) of 1400 chest CTs (200 consecutive within each age group: <40, 40-49, 50-59, 60-69, 70-79, 80-89, ≥90).

Spontaneous coronary artery dissection in cutis laxa.

We describe the case of a 21-year-old female with Cutis Laxa presenting with an acute coronary syndrome. A CT coronary angiogram (CTCA) diagnosed spontaneous coronary artery dissection (SCAD) of the right coronary artery, which was successfully managed with medical therapy. Cutis Laxa is a rare connective-tissue disorder in which the skin becomes inelastic.

Impact of an ultra-low dose unenhanced planning scan on CT coronary angiography scan length and effective radiation dose.

Objective: Imaged scan length (z-axis coverage) is a simple parameter that can reduce CT dose without compromising image quality. In CT coronary angiography (CTCA), z-axis coverage may be planned using non-contrast calcium score scan (CaCS) to identify the relevant coronary anatomy. However, standardised Agatston CaCS is acquired at 120 kV which adds a relatively high contribution to total study dose and CaCS is no longer routinely recommended in UK guidelines.

Computed tomography-derived fractional flow reserve (FFR) has no additional clinical impact over the anatomical Coronary Artery Disease - Reporting and Data System (CAD-RADS) in real-world elective healthcare of coronary artery disease.

Aim: To evaluate the impact of computed tomography-derived fractional flow reserve (FFR) compared to the anatomical Coronary Artery Disease - Reporting and Data System (CAD-RADS) in the elective assessment of coronary artery disease in real-world cardiology practise.

Materials And Methods: A retrospective review was undertaken of 1,239 coronary CT examinations from August 2018 to December 2019 with a minimum follow-up period of 1 year. Coronary disease was classified according to the CAD-RADS system.
