摘要:
For Tc-99m colloid bleeding studies to be positive, the patient must be actively bleeding while the colloid is circulating in the blood pool. A simple technique of sequential dose injections (SDI) is presented where five injections of 2 mCi each are made at 5-minute intervals. Image acquisition is performed after each injection. This technique results in an increase in the effective plasma residence time of the colloidal particles from 10-15 minutes to 35-40 minutes. A case report is presented in which the bleeding site was identified only after the fifth serial injection of a fractionated dose of Tc-99m microaggregated albumin colloid.

摘要:
Previous reports have shown that TI-201 myocardial imaging with either an oral or intravenous administration of dipyridamole is a suitable diagnostic examination for patients at risk for coronary artery disease who cannot perform treadmill exercise. To compare the incidence of complications associated with these two routes of drug administration, the records of 78 oral and 97 intravenous dipyridamole TI-201 imaging studies were reviewed. The oral administration is associated with a significantly higher incidence of nausea (15% vs. 4%). Despite the higher incidence of nausea, the percentage of patients having one or more dipyridamole-induced symptoms was no greater for the oral (29%) than for the intravenous (37%) administration. Intravenous administration produced both a significantly higher incidence of atypical angina (14% vs. 4%) and a significantly greater increase in heart rate (16.6 vs. 10.2 beats per minute). No patient in either the oral or intravenous dipyridamole protocols had life-threatening arrhythmias or myocardial infarctions. In clinical practice, the difference in complications associated with the oral and intravenous administration of dipyridamole for TI-201 imaging is not significant.

摘要:
Acute radiation nephritis typically affects the kidneys 3-12 months after radiation exposure and may occur with doses as low as 2500 rads. After an initial latent period, the affected portions of the kidneys become swollen and edematous, and develop multiple petechiae. Necrotizing vasculitis and interstitial hemorrhage occur, and the end stage is that of scarring. Two patients are presented in whom localized acute radiation nephritis developed, and whose kidneys demonstrated the characteristic sequential changes of this entity on serial bone imaging.

摘要:
One hundred thirty-six patients with suspected thyroid malignancy were studied prospectively with Ga-67 imaging of the thyroid and whole body. All patients subsequently had diagnoses proven by biopsy or surgical resection. Patients with malignant tumors (anaplastic carcinoma, malignant lymphoma, adenocarcinoma, medullary carcinoma, adenocarcinoma with squamous cell transformation, and metastases to the thyroid from other tumors) were examined serially after appropriate therapy. The authors draw on their own experience and a literature review to propose the following indications for Ga-67 imaging in patients with thyroid disease: 1) suspected anaplastic carcinoma or malignant lymphoma of the thyroid gland, 2) detection of distant metastases of anaplastic thyroid carcinoma and malignant lymphoma, 3) evaluation of efficacy of therapy, 4) suspected metastases to the thyroid gland from other malignancies, and 5) differentiation of malignant lymphoma from chronic thyroiditis. The strengths, limitations, and potential pitfalls of the technique are discussed.

摘要:
Radionuclide flow studies, planar, and SPECT hepatic blood pool imaging were peformed in 23 patients with 39 hepatic hemangiomas, 23 patients with primary and secondary liver tumors, 12 patients with hepatocellular disease, two patients with hepatic cysts, and 10 patients with no evidence of liver disease. The hepatic SPECT imaging identified all 39 hemangiomas as having a sequestration pattern compared with a yield of 69% (27 of 39 cases) for the planar imaging. None of the 47 other patients demonstrated this pattern. The SPECT approach is considered superior to planar blood pool imaging because of improved diagnostic yield, reduced patient imaging time, and greater ease of correlation with other cross-sectional imaging modalities.

摘要:
In addition to diagnosing acute cholecystitis, hepatobiliary imaging offers a noninvasive, physiologic, highly sensitive, and apparently underutilized technique for the evaluation of biliary leaks. As this case report illustrates, radionuclide imaging can play an important role in the diagnosis and follow-up of postcholecystectomy biliary leaks, particularly those treated by percutaneous catheter drainage.

摘要:
Two patients with pancreatitis in whom an area of predominant uptake of Ga-67 citrate was demonstrated involving the entire pancreas are presented. Ultrasound and x-ray CT did not reveal any morphologic abnormalities in the pancreas, whereas Ga-67 citrate imaging indicated the presence of active inflammatory change. Ga-67 citrate imaging may be useful in confirming the diagnosis of acute pancreatitis or acute exacerbation of chronic pancreatitis based on clinical and laboratory data, especially when ultrasound and/or x-ray CT cannot reveal any morphologic abnormalities in the pancreas.

摘要:
Hemangiopericytoma is a soft tissue tumor composed histologically of pericytes of Zimmerman, which line capillaries. These neoplasms have been observed throughout the body in soft tissue and bone. Presented here is a case of abdominal hemangiopericytoma proven histologically that simulated an accessory spleen on a number of studies including Tc-99m sulfur colloid imaging.

摘要:
An unusual case of Osteopoikilosis was found in a 52-year-old black woman. The rather large diffuse focal increased densities involving the ribs, spine, and pelvis as seen in the roentgenograms were believed to represent metastatic bone lesions. The normal nuclide bone images helped revise the diagnosis to osteopoikilosis. Early recognition of osteopoikilosis would have prevented the patient's apprehension and the extensive work-up for the primary tumor.

摘要:
Radionuclide arthrography is becoming increasingly useful in the evaluation of femoral component loosening in patients with a painful total hip prosthesis. Additional potential advantages of radionuclide arthrography include detection of abnormal communications with the hip, such as bursae, abscess cavities, and fistulas. A case of cutaneous fistula communicating with the hip in a patient with loosening and infection of the femoral component of the total hip prosthesis that is clearly demonstrated by radionuclide arthrography is presented.
