Characterization of complex coronary artery stenosis morphology by coronary computed tomographic angiography.

Objectives: This study sought to assess the ability of coronary computed tomography angiography (CTA) in identifying complex coronary stenosis morphology before invasive coronary angiography (ICA) and percutaneous coronary intervention (PCI).

Background: Complexity of stenosis morphology affects PCI success. Whether CTA can detect the entire spectrum of recognized complex stenosis morphologies has not been investigated.

The role of magnetic resonance imaging in determining the proximal extension of early stage cervical cancer to the internal os.

Purpose: To study the interobserver variability of MRI for visualization of the internal os and measuring the distance between tumor and the internal os in patients with early cervical carcinoma and to compare the distance between tumor and the internal os measured on MRI with invasion of the internal os determined by histopathology.

Materials And Methods: All T2-weighed MRI examinations between January 2003 and December 2007 of patients who underwent hysterectomy, of ≤40 years, with clinical stage IB1 cervix carcinoma and tumor size ≤2cm were retrieved. 27 patients fulfilled these criteria.
