which grew to 28 mm at 12-month CT screening (B2). A 56-year-old patient with a multilocular cyst containing a solid component at baseline (B3, arrow) that grew on follow-up screening (B4, arrow). Multilocular cysts that grow (> ...
In many instances, the CMR protocol may be shortened to address the clinical question; however, it is still a longer examination than a CT scan. However, CMR may be helpful in selected patients with suspected cardiac trauma and equivocal echo findings. MRI Heart With Function and Inotropic ...
CT venography (CTV) represents an alternative diagnostic study for many peripheral vascular interventions. However, it carries practical and logistical limitations in dialysis access imaging. There is no relevant literature to support the use of CTV with intravenous (IV) contrast in the evaluation of ...
CT and MRI When performed for liver lesion evaluation, a CT protocol may include multiple phases: unenhanced imaging and late arterial, portal venous, and delayed-phase postcontrast imaging. If a dual-energy CT (DECT) examination is performed, the unenhanced CT phase should be eliminated 67, ...
In general, women and health care professionals prefer intensive screening and surveillance after a diagnosis of breast cancer. Screening protocols include conventional imaging such as chest radiography, bone scan, ultrasound of the liver, and MRI of brain. It is uncertain whether PET/CT will serve...
Advancements in CT technology, in particular the development of wide-area detectors with greater z-axis coverage and dual-source CT, have improved functional assessment of the myocardium using stress CTP. Myocardial CTP has been validated in patients with acute and chronic chest pain against modalitie...
