Cases with imaging MRI

magnetic resonance imaging (mri)

basic physical principles of nuclear magnetic resonance imaging (n.m.r.i), a nonionizing medical imaging technique, are described. principles of nmri with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. t1 and t2 and spin density (s.d.) factors and different image construction techniques based on their different combinations is discu...

Fetal Gastrointestinal Imaging with MRI

Introduction: Although magnetic resonance imaging (MRI) of the fetus was sometimes used for the fetal imaging in the past, its usefulness was limited by the fetal motion arising from long acquisition times of MRI. The recent prevalence of prenatal MRI has been associated with the developments of ultrafast MR technique such as single-shot fast spin-echo sequence (SSFSE, GE). The SSFSE sequence i...

4D flow imaging with MRI.

Magnetic resonance imaging (MRI) has become an important tool for the clinical evaluation of patients with cardiovascular disease. Since its introduction in the late 1980s, 2-dimensional phase contrast MRI (2D PC-MRI) has become a routine part of standard-of-care cardiac MRI for the assessment of regional blood flow in the heart and great vessels. More recently, time-resolved PC-MRI with veloci...

Whole-body imaging with PET/MRI.

Whole-body positron emission tomography (PET) scanning with the radiolabeled glucose analogue 2-[fluorine-18]-fluoro-2-deoxy-D-glucose ( superset 18 F-FDG) can identify areas of cancerous involvement and distinguish malignant from benign lesions and therefore, plays an important role in the diagnosis and management of patients with cancer. PET facilitates the evaluation of metabolic and molecul...
