Abbiamo studiato con sequenze convenzionali e pesate in diffusione 12 pazienti con
sintomi clinici di ischemia acuta, per valutare la sensibilità delle varie sequenze in acuto, e …

The paper investigates the efficacy of diffusion weighted magnetic resonance imaging (MRI)
in the diagnosis of acute ischemic infarction and correlate the signal changes observed in …

OBJECTIVE. The objectiveof thisstudywasto determinethe time courseof signalinten sity

Results We observed 3 groups. In group A (36% of the lesions), ADC mapping did not
change image interpretation. This group was subdivided into 3 subgroups. A1: T2 and DIF …

La RM di diffusione (DWI) e perfusione (PWI) sono da considerarsi tecniche di elezione
nello studio dell'ischemia acuta nell'uomo. La DWI permette infatti di evidenziare il danno …

BACKGROUND AND PURPOSE: Diffusion and perfusion MR imaging have been reported
to be valuable in the diagnosis of acute ischemia. Our purpose was to ascertain the value of …

• Patients with acute stroke are more likely to be confused, uncooperative and so are more
difficult to image with MR safely. This may preclude imaging in up to a third of cases.• …

Diffusion and perfusion weighted MRI have been widely used in ischaemic stroke. We
studied 17 patients in whom ischaemic areas showed an ischaemic core, an area of infarct …

The vast majority of restricted-diffusion abnormalities result from acute stroke, and as such,
the diagnosis may be problematic when this MRI feature results from other causes. Distinct …

The results of diffusion-perfusion RM studies in cerebrovascular diseases are reviewed in
this paper. We discussed the role of these techniques for the understanding of the …
