Ultrasound of the palpable abdominal mass. 1990

C S Barker, and D R Lindsell

Department of Radiology, John Radcliffe Hospital, Oxford.

A retrospective study was made of adult patients with a palpable abdominal mass referred by Hospital Practitioners to the ultrasound department over an 11 month period. One hundred and four patients were included in the study. Sixty-nine patients had an abnormality responsible for the clinically palpable mass and 35 patients did not . There was one false positive ultrasound diagnosis and one false negative. The correct organ of origin was suggested in 60 patients and the correct pathological diagnosis in 53 patients. The high positive predictive value (99%) and negative predictive value (97%) for the presence or absence of a lesion in these patients compare very well with the investigation of such patients by computed tomography and we suggest that ultrasound should be the initial investigation.

D011237	Predictive Value of Tests	In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D014463	Ultrasonography	The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.
