MDCT of abdominal pathology: difficult diagnoses and strategies for optimization

Dear MDCT.net users,

MDCT is considered the most efficacious and reliable technique for evaluating abdominal diseases characterized by nonspecific clinical signs and difficult radiological diagnosis.

Gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasms that arise in the smooth muscle of the gastrointestinal tract, most often in the stomach. The new Focus on, by Doctor Ciolina and Professor Laghi, reviews the value of contrast-enhanced MDCT in the detection and characterization of GISTs, and in the assessment of these patients’ prognosis and response to therapy. The accompanying clinical cases illustrate other abdominal diseases of difficult radiological diagnosis.

The use of iodinated contrast medium for MDCT of the gastrointestinal tract in particular conditions needs special attention: the review and the e-lecture proposed in this Newsletter examine some optimization strategies related to the administration of contrast medium and CT imaging.

To suggest new topics to be covered in future issues, write to us at editorial@mdct.net.

Optimization of kVp and mAs in contrast and non-contrast CT examinations
JF. Paul

Lowering radiation exposure during CT examinations increases image noise, with the risk that image quality may be insufficient for diagnostic purposes. A trade-off is necessary between radiation dose reduction and image quality preservation. Some recent studies and new technical advances can help us choose the best combination of kVp–mAs pair. view »
