The use of gallium scanning for the diagnosis of abdominal abscesses was studied in 59 cases in which the diagnosis was verified by laparotomy or autopsy. In 23 of the cases the patients were subsequently found to have abdominal abscesses and 11 patients had abdominal malignancies. Excluding the latter group, the scan was specific for abscess in 86 per cent of the cases and sensitive for abscess in 67 per cent. Recent abdominal incisions, concurrent intestinal, hepatic, biliary and pancreatic inflammatory conditions, without abscess, seldom caused gallium accumulation. False-negative scans (18 per cent) occurred more frequently than false-positive scans (8 per cent) and were seen in patients with large (often palpable) masses of short evolution and with secondarily infected lesions such as hematomas and pseudocysts. The gallium scan was of little help in the search for abdominal lesions in patients with obscure febrile illnesses without abdominal symptoms or signs.
对59例经剖腹手术或尸检证实诊断的患者进行了镓扫描用于诊断腹部脓肿的研究。其中23例患者随后被发现患有腹部脓肿，11例患者患有腹部恶性肿瘤。排除后一组，扫描对脓肿的特异性为86%，敏感性为67%。近期腹部手术切口、并存的无脓肿的肠道、肝脏、胆道和胰腺炎症情况很少引起镓聚集。假阴性扫描（18%）比假阳性扫描（8%）更常见，见于病程短的大肿块（常可触及）患者以及继发感染的病变如血肿和假性囊肿患者。镓扫描对无腹部症状或体征的不明原因发热性疾病患者寻找腹部病变帮助不大。
