scintigram Med.|ˈsɪntɪgræm|
Also scinto-.
[f. scintillation + -gram.]
An image or other record of part of the body obtained by measuring radiation from an introduced radioactive tracer by means of scintillation or an analogous detection method.
1952F. K. Bauer et al. in Jrnl. Lab. Clin. Med. XXXIX. 153 It is suggested that this type of picture or visualization of a radioactive area be called a ‘scintigram’ and that specifically in this case they be called ‘thyroid scintigrams’. 1963Leader & Stell in M. F. Campbell Urol. (ed. 2) I. vii. 238 The renal scintogram does not distinguish cyst from tumour, and lesions smaller than 3 cm. in diameter cannot be picked up. 1971Emmett & Witten Clinical Urogr. (ed. 3) III. xx. 2041/1 To localize radioactivity graphically by moving external counting probes or by scintillation camera-type detectors, producing a cartographic image known as a scintigram or scintiscan. Ibid. 2064/2 The hippurate scintigram reveals the presence of abnormal kidneys. 1974R. M. Kirk et al. Surgery iv. 66 A scanner or gamma camera may be used to map out the distribution of radio⁓activity in a body, producing a diagram or ‘scintigram’. 1980Brit. Med. Jrnl. 29 Mar. 883/2 Bone metastases may be detected early as areas of increased isotope uptake (‘hot spots’) on scintigrams.
Hence ˈscintigraph, (a) a device for producing scintigrams; (b) a scintigram; scintiˈgraphic a., of, done by, or pertaining to scintigraphy; scintiˈgraphically adv., by means of scintigraphy; scinˈtigraphy, the production and use of scintigrams.
1958Strahlentherapy CV. 257 Scintigraphy and the use of collimaters provide the means of portraying true size and form of the thyroid. 1960Radiology LXXIV. 913/1 (caption) X-ray exposure is made during the scintigraphic procedure. Ibid. 914/1 Metastases in the right hepatic lobe can be scintigraphically demonstrated with only slightly less definition than in the left. 1961Med. Radiol. VI. x. 76 Scintigraph. A. Stefanovich. Summary. A short description is given of a design of the apparatus used to investigate the localisation of radioactive isotopes in the human body. 1975Sci. Amer. July 42/3 A scintigraph is an image constructed by a computer from the signals of many scintillation detectors arranged to detect the annihilation gamma rays in coincidence. For example, a patient can inhale nitrogen containing the positron-emitting isotope nitrogen 13. The scintigraphs clearly show how the gas enters the wind⁓pipe, passes through the bronchi and finally reaches the alveoli..in the lung. 1976New England Jrnl. Med. CCXCV. 1/1 We have previously reported on scintigraphic visualization of myocardial infarction in man with use of thallium-201. 1977Lancet 8 Jan. 92/2 (caption) Scintigraphs of left thigh showing localisation of Tc-99 diphosphonate in soft tissue. Ibid. 7 May 1012/2 Amyloidosis should be suspected when scintigraphy with Tc-99m diphosphonate shows a positive activity of soft tissues. 1978Jrnl. R. Soc. Med. LXXI. 39 Lesions in the pubis and ischium may be very difficult to detect scintigraphically. |
