The study of CSF flow became one of Phase-contrast MRI's major applications. The key to Phase-contrast MRI (PC-MRI) is the use of a bipolar gradient. [4] A bipolar gradient has equal positive and negative magnitudes that are applied for the same time duration.
Cisternography is a medical imaging technique to examine the flow of cerebrospinal fluid (CSF) in the brain, and spinal cord. [1] [2] The gold standard for diagnosis of a cranial cerebrospinal fluid leak is CT cisternography. [2] For the diagnosis of a spinal CSF leak radionuclide cisternography also known as radioisotope cisternography is used ...
Whereas the word "cine" (/ ˈ s ɪ n i /) in general usage refers to cinema (that is, a movie) [52] [54] or to certain film formats for recording such a movie, in medical usage it refers to cineradiography or, in recent decades, to any digital imaging mode that produces cine-like moving images (for example, newer CT and MRI systems can put out ...
A CMR study typically comprises a set of sequences in a protocol tailored to the specific indication for the exam. [21] A study begins with localisers to assist with image planning, and then a set of retrospectively-gated cine sequences to assess biventricular function in standard orientations.
Cinematography (from Ancient Greek κίνημα (kínēma) 'movement' and γράφειν (gráphein) 'to write, draw, paint, etc.') is the art of motion picture (and more recently, electronic video camera) photography.
T 2 *-weighted sequences are used to detect deoxygenated hemoglobin, methemoglobin, or hemosiderin in lesions and tissues. [2] Diseases with such patterns include intracranial hemorrhage, arteriovenous malformation, cavernoma, hemorrhage in a tumor, punctate hemorrhages in diffuse axonal injury, superficial siderosis, thrombosed aneurysm, phleboliths in vascular lesions, and some forms of ...
The physician controls both the contrast injection, fluoroscopy and cine application timing so as to minimize the total amount of radiocontrast injected and times the X-ray to the injection so as to minimize the total amount of X-ray used. Doses of radiocontrast agents and X-ray exposure times are routinely recorded in an effort to maximize safety.
This chart shows some of the design flow options for home theatre in the 2000s. In the 2010s, many home cinema enthusiasts aim to replicate, to the degree that is possible, the cinema experience. To do so, many home cinema buffs purchase higher quality components than used for everyday television viewing on a relatively small TV with only built ...
