perimesencephalic subarachnoid hemorrhage progressive macular hypomelanosis: PMI: point of maximal impulse or apical beat point of maximal intensity PML: polyoma virus progressive multifocal leukoencephalopathy PMP: Pseudomyxoma peritonei: PMN: polymorphonuclear leukocytes, that is, neutrophils PMR: percutaneous myocardial revascularization ...
Doppler ultrasonography is medical ultrasonography that employs the Doppler effect to perform imaging of the movement of tissues and body fluids (usually blood), [1] [2] and their relative velocity to the probe. By calculating the frequency shift of a particular sample volume, for example, flow in an artery or a jet of blood flow over a heart ...
Magnetic resonance imaging alias Nuclear magnetic resonance : high strength (0.15 to 1.5 teslas) [4] are used to excite protons that produce the record results (like CT scan). It can show particular tissues more clearly than CT.; [4] video link: Linear accelerator: used in radiotherapy for cancer: Functional magnetic resonance imaging (fMRI ...
In these studies, individuals ranging from about 15–40 years of age were examined and the majority of those tested were male. After each migraine episode, the patients were all asymptomatic. When examined via EEG, CT, and MRI forms of imaging, the CT and MRI scans were all normal; however, 30 out of 42 patients had abnormal EEG scans. [3]
Van Gijn maintains that in a perimesencephalic haemorrhage, good quality CTA is sufficient to exclude aneurysms. JFW | T@lk 11:02, 20 June 2008 (UTC) perimesencephalic SAH - should say blood is limited to sub-archnoid spaces around midbrain Done I believe this qualification is made in the "causes" section. I will rephrase it slightly.

The rastering of the beam across the sample makes STEM suitable for analytical techniques such as Z-contrast annular dark-field imaging, and spectroscopic mapping by energy dispersive X-ray (EDX) spectroscopy, or electron energy loss spectroscopy (EELS). These signals can be obtained simultaneously, allowing direct correlation of images and ...
