Subintimal
Refers to outside the intima layer of a blood vessel. The are three layers if tissue that make up the walls of a blood vessel, the intima (inner layer), the media and the adventitia. Subintimal typically refers to something between the intimal and medial layers,
susceptibility weighted imaging
aka BOLD (blood-oxyegen-level dependent) image or BOLD venography. This is a MRI imaging technique that is extremely sensitive to venous blood, hemorrhage and iron storage. It is particularly good at imaging venous blood.
susceptibility-weighted
aka BOLD (blood-oxyegen-level dependent) image or BOLD venography. This is a MRI imaging technique that is extremely sensitive to venous blood, hemorrhage and iron storage. It is particularly good at imaging venous blood.
SV-40
Simian Virus 40 or Simian vacuolating virus 40 – a polyomavirus that is found in both monkeys and humans. As with other polyomaviruses, it is a DNA virus that can cause tumors.
SWI
aka BOLD (blood-oxygen-level dependent) image or BOLD venography. This is a MRI imaging technique that is extremely sensitive to venous blood, hemorrhage and iron storage. It is particularly good at imaging venous blood.
Swischuk Line
This is the line drawn from the anterior aspect of the posterior arch of C1 to the anterior aspect of the posterior arch of C3. If the anterior aspect of the posterior arch of C2 is more than 2 mm anterior to this line it indicates a subluxation of C2 as would occur with a Hangman’s fracture.
syncytial
A multinucleated mass of cytoplasm. From the word syncytium (/sɪnˈsaɪtiəm/; plural syncytia; from Greek: σύν (syn) = “together” + κύτος (kytos) = “box, i.e. cell”). It results from fusion of a number of cells containing single nuclei.
syrinx
An abbreviation of syringomyelia, a fluid filled cavity within the spinal cord.
T & C
Type and Cross Match. As in type and cross match blood to possibly be used for a blood transfusion. Refers to the evaluation of a unit of donated blood for its “blood type” and whether it contains abnormal antibodies that might cause an adverse reaction if used in a transfusion.
