  13. Surgical suffixes, haemtology,diagnostic imaging

  14. Objectives By the end of the lecture you will • Name some surgical suffixes and state their meanings. • State medical terms for colours and conditions in which they occur. • State the types of blood cells and some of their disorders. • Name common diagnostic imaging techniques.

  15. : • SURGICAL SUFFIXES

  16. TOMOS = cutting • Greek tomos= cutting. Surgeons cut. • Suffixes from tomos: • -tome: instrument that cuts slices • -ectomy : ect = outside,+ tomos =cut. To cut out, to excise • -tomy: tomos . To cut into, to incise • -ostomy : os =mouth + tomos. To make a surgical (artificial) opening.

  32. When you see Tomos think of cut or cutting.

  33. DIAGNOSTIC IMAGING

  34. DIAGNOSTIC IMAGING • Radiologists also ‘cut’ in a way. They use xrays to take pictures or images of slices of the body. This process is called tomography. The xray picture or record is called a tomogram. The special xray machine is a tomograph.

  35. Tomo/graphy • The body is not actually cut to make these slices. The tom/o/graph (xray machine ) makes picture -like images that look like a cross-sectional slice.

  36. Tom/o/graph/y • A process that makes images of slices or planes of the body, using xrays. Analysis • Tom/o : combining form from tomos (Greek( to cut) + vowel-o- -graph: root word from Greek word graphein ( to write or record) –y : a noun suffix

  38. Exercise: some forms of diagnostic imaging and the and the medium they use

  39. Types of Tom/o/graph/y • MRI :magnetic resonance imaging • CT: computed tomography or • (CAT scan ( for axial) • PPET: positron emission tomography • SPECT :single photon emission tomography

  40. Oral exercise: To which of the 4 parts of terminology do these terms belong? • Tom/o/ • -graph • -y • radi/o • -ic

  41. Diagnostic imaging : Ultra/son/o/graphy. • Ultra= beyond • Son=word root (from Latin sonus= sound. • Son/o = combining form for sound. • a supersonic airplane is one traveling above the speed of sound. • -graph = machine used make a record. • -gram = the picture or record made. • -y = noun suffix • Recall – the suffix –ermeans one who.
