摘要:

Tc-99m-pyrophosphate myocardial scintigraphy was performed on 1,077 patients admitted to the Coronary Care Unit. Results of scintigraphy were compared to the diagnosis as established by ECG, enzymes, and clinical findings to determine the sensitivity and specificity of scintigraphy for the diagnosis of acute myocardial infarction (AMI). Scintigrams were graded according to the intensity of myocardial radioactivity and the distribution pattern of activity as either diffuse or localized. In a coronary care unit, a scintigram of positive intensity grade is 92% sensitive and 68% specific for the diagnosis for AMI. A localized pattern of myocardial radioactivity is 66% sensitive and 93% specific for AMI. With a localized pattern of the highest intensity, the sensitivity is 28% with a specificity of 99.8% for AMI. Therefore, a myocardial scintigram of normal intensity grade excludes the diagnosis of AMI with a 92% probability. A localized pattern is a strong indicator of an AMI and a localized pattern of the greatest intensity is very specific for AMI.

摘要:

Tc-99m-sulfur colloid reticuloendothelial images and percutaneous liver biopsies are correlated in 54 patients who presented with signs and symptoms of subacute hepatic necrosis or chronic active hepatitis. The scored Tc-99m-sulfur colloid scan is compared to the histological severity of disease. Serial scans and biopsies are compared. In patients with significant hepatocellular disease, the liver-spleen scan did not correlate well with the histological severity of disease. Changes in the spleen-to-liver ratio are more common than those in the liver or increased bone marrow activity, and appear earlier. In serial studies, changes in the Tc-99m-sulfur colloid scans correlate weakly with changes in histology.

摘要:

A patient is described in whom the postoperative management after renal transplantation was complicated by a wound discharge. A radionuclide technique of solving the clinical dilemma is discussed, using scintilymphangiography and qualitative assays.

摘要:

Metastatic pulmonary nodules from a well-differentiated hepatoma were well demonstrated by a Tc-99m-labeled hepatobiliary imaging agent. Uptake of this type of radionuclide by metastases from a primary hepatic malignancy has not previously been reported. Such radiopharmaceuticals may prove useful in the future as imaging agents for primary hepatobiliary tumors.

摘要:

Liver scans done at our Centre between 1964 and 1977 were analyzed with reference to hydatid cysts in liver. Among the approximately 7200 patients analyzed, there were 55 suspected to have hydatid cysts. The criteria adopted in screening the patients for hydatid cysts were based upon clinical findings and liver scan findings. The cases were analyzed with respect to their histologic findings, locations of cold areas in the liver, and correlation with Casoni's test. We found that 1) the cystic involvement was most often in the right lobe of the liver; 2) Casoni's test does not rule out or establish the presence of hydatidosis; 3) radioisotopic vascular studies done in some cases contributed to the diagnosis; 4) although a positive liver scan does not indicate the cause of the disease, the scans showing large and totally photon-deficient cold areas along with good general condition of the patients help in the diagnosis of hydatid cysts in the liver.

摘要:

A case of chronic osteomyelitis is presented in which bone scintigraphy with Tc-99m-MDP provided more accurate information than radiography in demonstrating the extent of the sequestrum and the involucrum response. Surgical and microscopic descriptions are included.

摘要:

Bone scans in patients with painful shin splints showed the “double stripe sign” which had previously been described as specific for hypertrophic pulmonary osteoarthropathy.
