| axial section | A cross section obtained by slicing, actually or through imaging techniques, the body or any part of the body structure, in a horizontal plane, i.e., a plane which intersects the longitudinal axis at a right angle. Since actual sectioning in the transverse plane results in an inferior and a superior portion, an anatomical transverse section may be a two-dimensional view of the cut surface on the inferior aspect of the superior portion, or of the superior aspect of the inferior portion. By convention, in medical imaging transverse sections demonstrate the former unless otherwise stated. Synonym: axial section. (05 Mar 2000) |

| axial skeleton | Articulated bones of head and vertebral column, i.e., head and trunk, as opposed to the appendicular skeleton, the articulated bones of the upper and lower limbs. Synonym: skeleton axiale. (05 Mar 2000) |
| axial surface | The surface of a tooth parallel with its long axis; the axial surface's are the vestibular (labial or buccal), lingual, and contact (mesial or distal). (05 Mar 2000) |
| axial view | Radiographic projection devised to obtain direct visualization of the base of the skull. Synonym: axial view, base projection, submental vertex projection, submentovertical projection, verticosubmental view. (05 Mar 2000) |
| axial walls of the pulp chambers | The wall's parallel with the long axis of a tooth: the mesial, distal, buccal, and lingual wall's. (05 Mar 2000) |
| computerised axial tomography | Cat scanning adds X-ray images with the aid of a computer to generate cross-sectional views anatomy. It can identify normal and abnormal structures and be used to guide procedures. CAT scanning is painless. Iodine-containing contrast material is sometimes used in CAT scanning. If you are having a CAT scan and are allergic to iodine or contrast materials, you should notify your physicians and radiology staff. (12 Dec 1998) |
| half-axial projection | Reverse tilted AP radiographic projection devised to permit demonstration of the entire occipital bone, foramen magnum, and dorsum sellae, as well as the petrous ridges. Synonym: half axial view, half-axial projection, Towne view. (05 Mar 2000) |
| half axial view | Reverse tilted AP radiographic projection devised to permit demonstration of the entire occipital bone, foramen magnum, and dorsum sellae, as well as the petrous ridges. Synonym: half axial view, half-axial projection, Towne view. (05 Mar 2000) |
| extra-axial | Off the axis; applied to intracerebral lesions that do not arise from the brain itself. (05 Mar 2000) |
| abscess scan | <investigation> This is a nuclear scan that utilises radioactively tagged white blood cells. The patients white blood cells (taken from a small tube of blood) are tagged with radioactive indium. Later, the cells are then reinjected into the bloodstream. The coarse of the white blood cells can then be mapped using a gamma camera (radiation detecting device). The net result is a picture that shows the location of the radioactive white blood cells. The location of the white cells can indicated the presence of infection or inflammation. This test is useful in detecting a hidden source of bacterial infection, such as an abscess. (11 Mar 1998) |
| biliary scan | <investigation, radiology> A test that uses a radioactive tracer to look for bile duct obstruction or gallbladder inflammation. A special tracer is injected into a vein that tends to collect primarily in the liver. It is then excreted in the bile where it makes its way to the gallbladder. A gamma camera measures the tracer (radioactivity) and generates an image of the gallbladder and biliary system. (27 Sep 1997) |
| bone scan | <investigation, radiology> A study of the body skeleton. A dose of radioactive substance is injected and the scan (taken a little time later) reads the distribution of the radioactivity. (16 Dec 1997) |
| bone scan: falsely negative metastases | <radiology> Anaplastic tumours, reticulum cell sarcoma, renal cell carcinoma, thyroid carcinoma, histiocytosis, neuroblastoma, multiple myeloma (positive scan usually due to recent or impending fracture) (12 Dec 1998) |
| captopril renal scan | <radiology> In a kidney with a lesion in the afferent arteriole (e.g. Atherosclerotic plaque), reflex constriction of the efferent arteriole occurs through angiotensin system thus maintaining renal perfusion. ACE inhibition prevents constriction of efferent arteriole. Therefore, perfusion is decreased to a kidney with afferent lesions and the renal scan to looks WORSE. Bottom line: renal scans appear WORSE with captopril administration if there is a lesion in the afferent arteriole. See: renal artery stenosis (12 Dec 1998) |
| gallbladder scan | <investigation, radiology> A test that uses a radioactive tracer to look for bile duct obstruction or gallbladder inflammation. A special tracer is injected into a vein that tends to collect primarily in the liver. It is then excreted in the bile where it makes its way to the gallbladder. A gamma camera measures the tracer (radioactivity) and generates an image of the gallbladder and biliary system. (27 Sep 1997) |
