Summary
Adding a coronal STIR sequence to lumbar spine MRI protocols can detect hip, pelvis, and sacrum lesions. This extended field-of-view scan reveals pathology missed by standard imaging, improving diagnostic yield.
Area of Science:
- Radiology
- Medical Imaging
- Orthopedic Imaging
Context:
- Standard lumbar spine MRI protocols often focus on sagittal and axial views.
- Pathology in adjacent structures like the hips, sacrum, and pelvis may be overlooked.
- The de Sèze projection is a known technique for visualizing the lumbar spine and pelvis.
Purpose:
- To propose an optimized MRI protocol for comprehensive lumbar spine evaluation.
- To highlight the benefits of incorporating a specific sequence for broader anatomical coverage.
- To improve the detection rate of lesions in the pelvis, sacrum, and hips.
Summary:
- The study recommends a coronal Short Tau Inversion Recovery (STIR) sequence with a large Field of View (FOV) as part of routine lumbar spine MRI.
- This sequence, similar to the de Sèze projection, extends imaging to include the hips, sacrum, and pelvis.
- It can identify lesions in these areas that are not visible on standard lumbar MRI sequences.
Impact:
- Enhances diagnostic accuracy by revealing otherwise undetected pathology.
- Improves patient care through more comprehensive imaging assessments.
- Offers a cost-effective method to increase the detection of significant lesions with minimal additional scan time.

01:24Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
01:27Imaging Studies IV: Magnetic Resonance Imaging
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
01:26Diamagnetism
Materials consisting of paired electrons have zero net magnetic moments. However, when these materials are placed under an external magnetic field, the moments opposite to the field are induced. Such materials are called diamagnets. Diamagnetism is the response of the diamagnets when placed in an external magnetic field.
Diamagnetism was discovered by Anton Brugmans in 1778 when he observed that bismuth gets repelled by magnetic fields, thus theorizing that diamagnets get repelled by magnets.

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
