Quantitative MRI assessment of leukoencephalopathy.
Quantitative MRI assessment of leukoencephalopathy is difficult because the MRI properties of leukoencephalopathy significantly overlap those of normal tissue. This report describes the use of an automated procedure for longitudinal measurement of tissue volume and relaxation times to quantify leukoencephalopathy. Images derived by using this procedure in patients undergoing therapy for acute l...
متن کاملQuantitative Assessment of Myocardial Perfusion MRI
Myocardial perfusion MRI is acquired with a T1-weighted dynamic MRI sequence. Fully quantitative analysis of myocardial perfusion MRI allows the absolute quantification of myocardial blood flow (MBF) through the use of complex mathematical modeling. There are essentially two main methods for quantification of absolute MBF: the linear time-invariant model and the compartment model. Maximized con...

متن کاملQuantitative MRI for the assessment of bone structure and function.
Osteoporosis is the most common degenerative disease in the elderly. It is characterized by low bone mass and structural deterioration of bone tissue, leading to morbidity and increased fracture risk in the hip, spine and wrist-all sites of predominantly trabecular bone. Bone densitometry, currently the standard methodology for diagnosis and treatment monitoring, has significant limitations in ...
متن کاملQuantitative assessment of myocardial motion from velocity encoded MRI
Methods 11 Volunteers (30±8 years) and 3 patients (41±11 years) were investigated at a 3T whole body MR scanner (Achieva, Philips) with a 32 channel cardiac coil. The patients suffered from DCM, asynchrony and/or LBBB. A velocity encoded (TPM) navigated segmented gradient echo sequence was applied in the apical, equatorial and basal slice. The acquisition parameters were: FOV=340mm, in-plane re...
