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 ...
Interventional neuroradiology (INR) also known as neurointerventional surgery (NIS), endovascular therapy (EVT), endovascular neurosurgery, and interventional neurology is a medical subspecialty of neurosurgery, neuroradiology, intervention radiology and neurology specializing in minimally invasive image-based technologies and procedures used in diagnosis and treatment of diseases of the head ...
A medical test is a medical procedure performed to detect, diagnose, or monitor diseases, disease processes, susceptibility, or to determine a course of treatment. The tests are classified by speciality field, conveying in which ward of a hospital or by which specialist doctor these tests are usually performed.
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.
Perfusion MRI or perfusion-weighted imaging (PWI) is perfusion scanning by the use of a particular MRI sequence [which? The acquired data are then post-processed to obtain perfusion maps with different parameters, such as BV (blood volume), BF (blood flow), MTT (mean transit time) and TTP (time to peak).
Endovascular coiling was a developed through the synthesis of a number of innovations that took place between 1970 and 1990 in the field of electronics, neurosurgery, and interventional radiology. [4] While the procedure itself has been and continues to be compared to surgical clipping, the development of the concept and procedure has resulted ...
