Diagnostic Investigations

The results of diagnostic and staging investigations in consecutive cases of invasive transitional cell carcinoma of the bladder are reviewed. Urine culture, urine cytology and intravenous urography had positive results in a high percentage of cases. As diagnostic investigations they are cost-effective but certainly do not remove the obligation to perform cystoscopy and examination under anaesthetic. Isotopic bone scan and liver scan showed metastases in 4 and one cases respectively and only when there were clinical signs of disseminated disease. Chest X-ray showed metastases in one case. These investigations are not cost-effective. Lymphangiography was positive in 12 of the 94 cases and, although expensive (£70), is still a staging investigation of value in planning treatment.

Liver-spleen scans on 254 children were reviewed retrospectively with regard to accuracy and yield of the examination. The scan predicted abnormality correctly 95% of the time and normality correctly 86% of the time. Pitfalls in interpretation include the nonspecificity of abnormalities present on the scan, confusion of extrinsic with intrinsic defects, and normal anatomical variations with pathology. The technetium-99m-sulfur colloid scan was found to be most helpful in diagnosing splenic abnormalities, in working up abdominal masses, and in evaluating tumor patients after a baseline scan. It was found least useful in patients with fever of unknown origin, abdominal pain, diffuse liver disease, and most inflammatory conditions. Liver abscesses were not found in febrile, otherwise healthy children. The iodine-131-rose bengal liver scan was found to be useful to differentiate potentially curable lesions (e.g., choledochal cysts) from those not surgically treatable.

The authors evaluate the combined use of liver scan and the CEA test in the diagnosis of hepatic metastases of carcinoma of the gastrointestinal tract. Association of the two tests is justified by the fact that the liver scan is very specific but not very sensitive, whereas the CEA test is more sensitive and not very specific. The sensitivity of the CEA test, on the other hand, can be increased by increasing the threshold of normality. However, the associated diagnostic use of the liver scan and the CEA test gives a loss of specificity with respect to the use of the liver scan alone. The present study, carried out on a series of 376 patients affected by gastrointestinal tumors of which 79 were of the stomach (9 with hepatic metastases), 133 of the colon and higher sigmoid (25 with hepatic metastases), and 164 of the lower sigmoid and rectum (29 with hepatic metastases), proposed to establish by use of a statistical method the optimal threshold of the CEA test that would give the best diagnostic specificity of the combined CEA test and liver scan without any relevant loss of sensitivity. A threshold of 26 ng/ml of the CEA test gave a specificity of 92 %, a sensitivity of 80 %, and an accuracy of 90 %. The authors think that in the detection of liver metastases of gastrointestinal tumors, the combined test can be more helpful the less the probability, for a given patient, for other metastatic localizations.

Liver Scanning

Nonalcoholic fatty liver disease (NAFLD) encompasses a wide spectrum of liver damage and is the most common cause of chronic liver diseases in Western countries. Although a relatively common condition affecting approximately 20% of the general population, NAFLD is especially prevalent in obese individuals, a figure likely to rise as obesity rates in Western countries continue to increase. Liver biopsy remains the gold standard diagnostic method; however, its invasive nature, among other factors, has prompted the need to develop less invasive, alternative methods to quantify hepatic fat and determine disease severity. Xenon-133 liver scanning is one such method that has been in use for more than 10 years in the evaluation of patients with suspected NAFLD. This study compared Xenon-133 liver scan with other currently used, invasive and noninvasive methods of liver assessment.BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is an important and common condition affecting approximately 20% of the general population. Given the limitation of radiological investigations, diagnosis often requires a liver biopsy.OBJECTIVE: To compare Xenon-133 (Xe-133) liver scanning with ultrasonography in the diagnosis of NAFLD.METHODS: From January 2003 to February 2007, 258 consecutive patients with suspected NAFLD underwent Xe-133 liver scanning at Royal Victoria Hospital (Montreal, Quebec). Of these, 43 patients underwent ultrasonography and liver biopsy for the evaluation of NAFLD. Patients with other liver diseases and significant alcohol consumption were excluded. Two nuclear medicine physicians assessed liver Xe-133 uptake and measured the grade of steatosis using a standardized protocol. The degree of steatosis was determined from biopsy specimens assessed by two hepatopathologists.RESULTS: NAFLD was identified by liver biopsy in 35 of 43 patients (81.4%). Xe-133 scan demonstrated 94.3% sensitivity (95% CI 81.4% to 98.4%) and 87.5% specificity (95% CI 52.9% to 99.4%) for the presence of NAFLD. The positive and negative predictive values for detection of steatosis by Xe-133 scan were 97.1% (95% CI 85.1% to 99.8%) and 77.8% (95% CI 45.3% to 93.7%), respectively. The positive and negative likelihood ratios were 7.54 (95% CI 1.20 to 47.26) and 0.07 (95% CI 0.02 to 0.26), respectively. Two patients with NAFLD (5.7%) who had a negative Xe-133 scan result had histologically mild steatosis (<10%). The grade of steatosis on liver biopsy was highly correlated with the results of the Xe-133 scan (r=0.87; P<0.001). The sensitivity and specificity of ultrasound in diagnosing steatosis were 62.9% and 75%, respectively.CONCLUSION: Xe-133 liver scan proved to be a safe, reliable, non-invasive method for diagnosing and quantifying hepatic steatosis, and was superior to ultrasound.

The diagnostic accuracy of clinical studies done in 38 patients with small cell carcinoma of the lung was analyzed by comparing the test results to autopsy findings. The chest radiograph was accurate in 31 of 38 patients (82%). The accuracy of the chest radiograph was higher in evaluating the lung parenchyma and mediastinum than in evaluating the hilum and pleura. Computerized tomographic brain scan was accurate in 11 of 12 patients. However, all the diagnostic studies used for assessing the liver, including physical examination, serum liver enzyme and bilirubin measurements, and radionuclide liver scan, were only moderately accurate. More accurate studies for detecting liver metastasis in patients with small cell carcinoma are needed.
