Brain Abscess: (Left) axial CT scan with contrast; (Right) T1-weighted with gadolinium coronal MRI. Note the ring enhancement both on the CT and MRI scans surrounding a central necrotic cavity. This ...

MRI provides ... changes signal intensities by shortening T1. Thus, Gad is very bright on T1-weighted images. Gad enhanced images are especially useful in looking at vascular structures and breakdown ...

Panel D demonstrates how the diagnosis in this patient was finally made with MRI, which shows an anterior spinal epidural abscess at L4 (arrow) associated with osteomyelitis of L3 and L4 and L3 ...

The MRI signal is measured relative to normal brain ... Mr Laurie's results indicated he was hosting an abscess the size of an apple. "It would have been fatal within three or four days if we ...

A subsequent MRI scan shows that the signal abnormalities in the dentate nuclei have resolved (Panel B). A 74-year-old man with metastatic carcinoid tumor and intraabdominal abscesses that had ...

Nov. 12, 2004 — Dynamic susceptibility contrast perfusion MRI can distinguish between cerebral abscesses and high-grade neoplasms, according to the results of a preliminary study published in ...

An MRI scan often generates an ocean of data, most of which is never used. When overlooked data is analyzed using a new technique developed at Washington University School of Medicine in St. Louis ...

Patients with enthesopathy of the extensor carpi radialis brevis who had symptomatic and asymptomatic elbows commonly had increased MRI signal, according to recently published results. To identify ...

The onion on the right rested on top of a "magnetic metamaterial" that enhanced the MRI signal. The onion on the left did not have the signal boosting device. (Courtesy of Xin Zhang) Using ...
