摘要:
The usefulness of ln-111 labeled white cells in acute infection is well documented but the role of Tc-99m labeled white cell scintigraphy (WCS) has not been as clearly established. Using stannous fluoride colloid and a simple labeling procedure with 20 ml of autologous whole blood, three cases are presented in which Tc-99m WCS established unexpected diagnoses in patients who had remained undiagnosed despite extensive investigation.

摘要:
The role of technetium-99m pertechnetate imaging in acute testicular torsion is well appreciated. Manual testicular detorsion under local anesthesia may be performed in the nuclear medicine clinic by the urology service immediately following initial diagnostic scintigraphy. Following manual testicular detorsion, continued images of the testes are obtained up to 30 minutes without having to reinject the patient with technetium-99m pertechnetate. Reperfusion of the affected testicle will be dramatically noted if the manual detorsion is successful. Four cases are presented to illustrate this.

摘要:
The authors have developed a method to estimate the 24-hour sodium iodide thyroid uptake based on a 5-minute Tc-99m pertechnetate thyroid uptake using the equation: Estimated Iodide Uptake = 17.72*In(Pertechnetate Uptake) + 30.40. This estimation has a correlation coefficient of 0.90. It is based on a data pool of 44 patients who underwent I-131 and Tc-99m studies within 2 weeks of each other from 1978-1988, with established diagnoses as follows: 12 euthyroid, 6 hyperthyroid with multinodular goiters, 15 hyperthyroid with diffuse goiters, 4 with subacute thyroiditis, and 7 unknown. The population consisted of 30 women and 14 men with a mean age of 52.0 ± 17.5 years; this sample was screened for use of thyroid hormone, propylthiouracil, and radiographic contrast. The authors believe this estimation method is of value whenever a 24-hour iodide uptake is desired, and where speed and minimizing radiation dose are factors. This method is strongly recommended for thyroid uptake evaluation before I-131 therapy.

摘要:
To study the incidence of pulmonary embolism (PE) in elderly patients newly admitted to an acute geriatric unit, the authors carried out ventilation perfusion scans on 33 patients, 25 women and 8 men, mean age 79 years, consecutively admitted to the geriatric wards. The first scan was done within 5 days of admission and repeated between days 10 and 20. Where possible, patients with a positive second scan had a repeat scan at 2-3 months. Six (18%) patients were found to have a high probability of PE, 4 (12%) at the time of admission and two (6%) after admission. Three patients (9%) were considered to suffer from chronic pulmonary artery disease. Mortality was 5 for the whole group (15%) and 1 of 6 (17%) with a high probability of PE; this patient was suffering from carcinomatosis. The only patient who was anticoagulated suffered serious side effects. In no patient was PE clinically suspected. The authors conclude that PE is common in sick elderly patients newly admitted to acute geriatric wards, that rehabilitation with mobilization may precipitate new PE, and that nonanticoagulated PE does not seem to appreciably shorten the prognosis for life. Treatment with anticoagulants may be more dangerous than not treating PE in this older age group.

摘要:
The detection of renovascular disease (RVD) has particular relevance in hypertensive patients (HP) who have symptoms of target organ damage. To evaluate the possibility of RVD in HP undergoing myocardial perfusion scintigraphy for chest pain symptoms, posterior renal images were obtained at 1-3 hours after TI-201 injection. Analog and computer images were obtained for 5 minutes in 45 HP; 12 patients with no history of hypertension or renal disease served as normal controls. For qualitative analysis, images were coded and read by three observers as to symmetry of renal uptake. Differential renal uptake of TI-201 (DRU) was quantitated on computer images. In normal controls, uptake was agreed on as symmetric. In HP, 6 patients had marked asymmetry of DRU and 4 had possibly significant asymmetry; 2 had decreased uptake in both kidneys suggesting bilateral RVD or nephrosclerosis.Objective correlation with DRU was obtained in 10 HP who had contrast angiography, confirming 4 cases of unilateral RVD and 2 of bilateral RVD. Thirteen patients also had renography with Tc-99m DTPA; differential renal function by this modality correlated well with DRU of TI-201 (r=0.98). Thus, DRU of TI-201 can be used as a supplement to myocardial scintigraphy to identify HP who require further evaluation and treatment of RVD.

摘要:
Serious complications of liver biopsy are uncommon with injury to the gallbladder being rare. Rapid diagnosis and proper management of injuries to the biliary system are necessary because of potential morbidity associated with bile peritonitis. Scintigraphy is an accepted means of evaluating traumatic injuries of the gallbladder and biliary tree. The authors present a case of iatrogenic perforation of the gallbladder during liver biopsy demonstrated by hepatobiliary scintigraphy. CT and surgical correlation are provided.

摘要:
Patients with ascites are known to have complications such as pleural effusions and hernias. Special diagnostic procedures are occasionally necessary to determine the nature of the abnormality and to determine the corrective medico-surgical approach. The two cases described illustrate the usefulness of intraperitoneal as well as intrapleural injection of a radionuclide in diagnosing the leakage of ascitic fluid.

摘要:
A patient presented with recurrent pheochromocytoma 10 years following the apparently successful surgical cure of a right adrenal pheochromocytoma. Conventional medical imaging techniques, (chest radiograph, abdominal ultrasound, and abdominal CT) suggested local recurrence for which surgery was planned. I-131 MIBG scintigraphy revealed disseminated metastatic disease that rendered attempts at surgical cure futile. The patient was treated with three therapeutic doses of I-131 MIBG with good symptomatic palliation and improvement of ome biochemical parameters.

摘要:
A case is presented in which uptake of Tc-99m MDP was noted at the sites of tendon and ligament attachments to the calcaneus in inflammatory enthesopathy. Following successful treatment with corticosteroids, the uptake was markedly decreased in accordance with subsidence of clinical manifestations and normalization of laboratory data. Radionuclide bone imaging may be useful in evaluating the response to treatment with corticosteroids as well as revealing the active disease sites in inflammatory enthesopathy.

摘要:
Radionuclide bone imaging using Tc-99m phosphates may show accumulation of activity in amyloid deposits. While many sites of amyloidosis have been detected with bone imaging, many reports center on cardiac amyloidosis. The case reported here demonstrates accumulation of Tc-99m MDP in amyloidosis involving the skin and muscle, including the tongue.
