MRI stands out among soft tissue imaging innovations
MRI stands out among soft tissue imaging innovations. The last half of the 20th century saw the development and refinement of several significant medical imaging technologies, including digital X-ray, nuclear medicine, ultrasound, positron emission tomography (PET) and computed tomography (CT).Arguably, however, magnetic resonance imaging(MRI) is distinguished in its superior capacity to resolve soft tissue details. No other technique, short of physical dissection, affords clinicians the opportunity to visualise morphology and pathology with suchexquisite spatial resolution. Structures and detail as small as a few tenths of millimetres in size can be distinguished, a critical benefit in helping physicians detect incipient disease. MRI also helps cliniciansdifferentiate normal tissues from pathology based on disparate soft tissue relaxation rates or even based on functional variations between tissues. Furthermore, MRI is the modality of choice in followup examinations to visualise disease recurrence or inmonitoring the impact of interventions.Importantly, MRI is not a static technology,particularly as it pertains to soft tissue imaging. As physicists and radiologists relentlessly probe the potential of MRI physics and how they can be harnessedfor imaging purposes, fascinating and usefulnew MRI techniques are always entering the clinical arena.
