Objective: To prospectively compare accuracies of transcranial color-coded duplex sonography (TCCS) and transcranial Doppler sonography (TCD) in the diagnosis of middle cerebral artery (MCA) vasospasm.
Design: Prospective blinded head-to-head comparison TCD and TCCS methods using digital subtraction angiography (DSA) as the reference standard.
Setting: Department of Radiology in a tertiary university health center in a metropolitan area.
Article Synopsis
- The study aimed to create and evaluate a magnetic resonance imaging (MR) strategy to differentiate between various types of intraaxial brain masses, using histology or clinical diagnosis as the reference.
- The research analyzed data from 111 patients, focusing on different types of brain masses such as primary neoplasms, abscesses, lymphomas, and others, and developed a comprehensive MR imaging approach combining multiple techniques.
- The findings showed high accuracy (90%), sensitivity (97%), and specificity (67%) in differentiating neoplastic from non-neoplastic diseases, with strong performance in identifying high-grade versus low-grade neoplasms and other specific conditions.
Intraaxial brain masses are a significant health problem and present several imaging challenges. The role of imaging is no longer limited to merely providing anatomic details. Sophisticated magnetic resonance (MR) imaging techniques allow insight into such processes as the freedom of water molecule movement, the microvascular integrity and hemodynamic characteristics, and the chemical makeup of certain compounds of masses.

Methods: We did a retrospective review of 143 normal abdominal helical computed tomography scans of individuals aged 50 years and older to measure the distance between the posterior aortic wall and anterior cortex of vertebral bodies from T12 through L3.
Results: The normal abdominal aorta maintains a close relationship to the vertebral column.
