Magnetic Resonance Imaging The classical technique for obtaining MR images is called spin echo.In this technique, a 90° radio frequency pulse is followed by a 180° pulse (the purpose

– immediately after the 90° pulse, a negative magnetic field gradient is applied; the spins start precessing at a position-dependant speed, dephas- ing in an “ordinate” manner with

Recent advances in magnetic resonance imaging and magnetic resonance spectroscopy imaging have the potential to offer better target delineation in multiple tumor sites and for

Magnetic resonance fluoroscopic images of the pelvis at rest (a), during squeeze (b), and simulated defecation (c) in a 52-year-old asymptomatic patient after filling the rectum

The sensitivity of MRI to breast carcinoma, particularly in dense breast tissue, has led to the emerging role of MRI in breast cancer screening for women identified to be at

Monitoring the effects of neoadjuvant therapy is impor- tant to assess effectiveness of chemotherapy after initial doses, thereby determining if a specific treatment should be

Spiculated and irregular masses (Figure 6.5) are suspicious for carcinoma, whereas a smooth margin is more suggestive of a benign lesion (Figure 6.6).. Margin analysis is dependent
