Objective: To determine the MRI-Linac added value over conventional imageguided radiation therapy (IGRT) in liver tumors Stereotactic ablative radiation therapy (SABR). Materials and methods: We retrospectively compared the Planning Target Volumes (PTVs), the spared healthy liver p...
Unlike X-rays and CT scans, MRIs don’t use damaging radiation. How MRIs Work The MRI is basically a tube-shaped magnet. While you're inside the machine, protons from water in your body get pulled into the magnetic field around you and start to line up. The machine also sends out rad...
Taken together, these results suggest that PET/MRI, which offers the advantage of decreased radiation exposure to the patient, is useful for diagnosing PIF and can detect it earlier than PET/CT imaging. Copyright: Azumi et al. 展开 关键词: insufficiency fractures magnetic resonance imaging ...

An MRI of the brain and spinal cord can help find many things, like: Blood vessel damage, including ananeurysm(a bulging or weakened blood vessel in the brain) Brain injury Cancer Multiple sclerosis (MS) Spinal cord injuries Stroke Eye problems ...
MRI safety Unlike other imaging forms like X-rays or CT scans, MRI doesn't use ionizing radiation. MRI is increasingly being used to image fetuses during pregnancy, and no adverse effects on the fetus have been demonstrated, Filippi said. ...
Five years ago, I had a magnetic(磁性的) resonance(共振) imaging scan, an MRIfor short. The problem thatjustifiedthe testturned outto be very minor, but the MRI revealed an unrelated(无关联的) issue called an acoustic(听觉的) neuroma(神经瘤). ...
Medical imaging is a central part of the improved outcomes of modern medicine. Different types of medical imaging procedures include: X-rays Magnetic resonance imaging (MRI) Ultrasounds Endoscopy Tactile imaging Computerized tomography (CT scan) ...

Thus, it is crucial to confirm abnormalities seen on the MRI with a biopsy. Evidence suggests that further surgery is not necessarily required for tiny regions of MRI-detected malignancy. Almost all women who have breast-conserving surgery will have radiation. Radiotherapy may effectively treat ...
