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...

Quality Assurance for Magnetic Resonance Imaging (MRI) in Radiotherapy

Thoracic Magnetic Resonance Imaging

Pediatric chest MRI faces many challenges. High resolution scans of the lungs and airways are compromised by long imaging times, low lung proton density signal and cardiac and respiratory motion. A low lung signal is problematic in imaging relatively normal lung tissue, but less so for diseased lung tissue. Indeed, various pathologic conditions often result in an increased signal from lung pare...

T2-Weighted 4D Magnetic Resonance Imaging for Application in Magnetic Resonance–Guided Radiotherapy Treatment Planning

OBJECTIVES The aim of this study was to develop and verify a method to obtain good temporal resolution T2-weighted 4-dimensional (4D-T2w) magnetic resonance imaging (MRI) by using motion information from T1-weighted 4D (4D-T1w) MRI, to support treatment planning in MR-guided radiotherapy. MATERIALS AND METHODS Ten patients with primary non-small cell lung cancer were scanned at 1.5 T axially ...
