Age-stratified Patterns of Thymic Involution on Multidetector CT.

Purpose: The aim of this study was to better assess the prevalence and appearance of thymic tissue in adults stratified by age using multidetector computed tomography (MDCT) in order to prevent misinterpretation of normal thymic tissue as pathology.

Materials And Methods: This study examined the CT appearance of the thymus in 597 trauma patients aged 30 to 69 years (M=48.0 y, SD=11.

Bladder trauma: multidetector computed tomography cystography.

Multidetector computed tomography (MDCT) cystography is rapidly becoming the most recommended study for evaluation of the bladder for suspected trauma. This article reviews the bladder trauma with emphasis on the application of MDCT cystography to traumatic bladder injuries using a pictorial essay based on images collected in our level I trauma center.

Splenic trauma: pictorial review of contrast-enhanced CT findings.

Splenic trauma is a common entity of high clinical significance that may have a variety of imaging manifestations. This article reviews splenic anatomy and function, mechanisms of splenic trauma, and the classification and grading of splenic trauma, with a particular focus on contrast-enhanced CT. Heterogeneous early enhancement of the spleen and technical suggestions to minimize this artifact are discussed.
