TL;DR: Timely and accurate diagnosis of life-threatening intraabdominal pathology is essential to care for critically ill patients and a multitude of laboratory, radiologic, and interventional modalities are available to evaluate the abdomen in the critically ill.
Abstract: Purpose of reviewEvaluation of the abdomen in critically ill patients can be challenging. This article reviews the available data and proposes evidence-based guidelines for evaluation of the abdomen in the critically ill patient.Recent findingsThe critically ill are often clinically unevaluable due

TL;DR: It is argued that a CT of the cervical spine must be supplemented by an additional examination addressing ligamentous instability in this patient population, and the evidence supporting CT for the stand-alone evaluation ofThe cervical spine in the unevaluable patient is insufficient.

TL;DR: In this article, the influence of the patient's heart rate during the scan on stenosis detection and the presence of motion artifacts was investigated and the number of unevaluable arteries increased and overall sensitivity decreased from 62% (HR 70 bpm), but evaluability and accuracy decrease with increasing HR.
Abstract: Multi-slice spiral CT (MSCT) permits the detection of coronary stenoses. We investigated the influence of the patient's heart rate (HR) during the scan on stenosis detection and the presence of motion artifacts. In 100 patients MSCT was performed and retrospectively ECG-gated cross-sectional images were reconstructed. 115 of 400 coronary arteries (29%) were unevaluable due to motion artifacts (84/115) or other reasons (31/115). In evaluable arteries, sensitivity was 91% (51/56 high grade stenoses detected), specificity was 89%. With increasing HR, the number of unevaluable arteries increased and overall sensitivity for stenosis detection decreased from 62% (HR 70 bpm). MSCT permits detection of coronary stenoses, but evaluability and accuracy decrease with increasing HR.
