摘要:

DISIDA imaging showed nonvisualization of the gallbladder in a patient with abscess adjacent to otherwise normal gallbladder. This adds to the gamut of reported causes of false-positive DISIDA scans.

摘要:

In the course of a work-up for fever of unknown origin associated with intermittent arrhythmias, a gallium scan was performed which revealed diffuse myocardial uptake. The diagnosis of Lyme disease myocarditis subsequently was confirmed by serologic titers. One month following recovery from the acute illness, the abnormal myocardial uptake completely resolved.

摘要:

The localization of ln-111 labeled leukocytes (WBCs) in recent surgical incisions was studied in 18 patients, ln-111 WBC images correlated well with culture results and clinical findings. No accumulation of ln-111 WBCs was detected at the site of noninfected incisions in nine patients, ln-111 WBCs did accumulate at incision sites in nine patients with infected surgical incisions. These results indicate that ln-111 WBC study can accurately distinguish between normal healing and infection of recent surgical incisions.

摘要:

To evaluate the contribution of Tc-99m pyrophosphate scintigraphy (TPS) on the overall management of patients suspected of having acute myocardial infarction (AMI), hospital records of 58 consecutive patients who underwent TPS, were evaluated in depth. The results indicate that TPS was essential for the diagnosis of AMI in 16% of the patients. TPS was most rewarding in perioperative patients and in patients with borderline or uninterpretable electrocardiographs and enzyme changes. Also, in some cases, TPS was able to confirm or exclude the diagnosis of AMI prior to the confirmation by serial electrocardiograms (ECG) and serial enzyme changes. TPS was less rewarding in patients with clinically low index of suspicion for AMI. It may also be confusing in patients with high clinical likelihood of AMI and a history of prior myocardial infarction because of the possibility of persistently positive TPS in some of these patients. Considering the limitations of ECGs, the cardiac enzymes, and atypical clinical presentations in the patient population we evaluated, TPS appears to be fairly accurate when the scintigraphic findings are compared with the final diagnosis at the time of discharge from the hospital.

摘要:

Eight cases of pulmonary embolism were evaluated with Ga-67 citrate scintigraphy. Of the eight patients, all but one showed evidence of abnormal Ga-67 citrate localization within involved regions of the lung as demonstrated by ventilation-perfusion lung scintigraphy. The sole patient who did not demonstrate Ga-67 localization within the lung had marked breast accumulation of the radiotracer which may have obscured lung parenchymal uptake. Since Ga-67 citrate is known to accumulate within inflammatory lung processes, this radiotracer would not have a specific role in differentiating pulmonary embolism from these conditions. This study disagrees with the results of other studies in the medical literature that describe such a role.

摘要:

Diffuse pulmonary uptake by bone-seeking radiopharmaceuticals has been reported previously but, in the same patient, would pulmonary uptake of Ga-67 citrate yield clinically meaningful results? A patient with hypercalcemia and renal failure in whom bone scintigraphy demonstrated striking diffuse bilateral pulmonary uptake, but subsequent gallium imaging demonstrated no evidence of pulmonary uptake greater than body background, is discussed. We conclude that pulmonary uptake of gallium cannot be attributed to calcium deposition and should carry the same clinical significance in regard to inflammatory and malignant lesions as would be assigned to patients without pulmonary calcific deposits.

摘要:

The inappropriate placement of a patient's central venous catheter in the pleural space by the serendipitous injection of Tc-99m labeled red blood cells through the catheter during a Gl bleeding study was discovered. Position and patency of central venous lines can be incidentally evaluated by using existing central venous catheters for administration of radiopharmaceuticals during radionuclide imaging studies.

摘要:

Scintigraphic evidence of ascites has been observed in Tc-99m sulfur colloid studies of the liver and spleen, in Tc-99m HIDA hepatobiliary scans, in Ga-67 citrate scans, and in Tc-99m phosphonate bone images. Pleural effusion has been demonstrated in Tc-99m phosphonate bone scintigraphy. The case of a 48-year-old man whose Tc-99m sulfur colloid liver-spleen scintigram simultaneously demonstrated a right pleural effusion and ascites is presented.

摘要:

The diagnosis of delayed rupture of the spleen is demonstrated and discussed by presenting a case in which the patient had significant thoracoabdominal trauma with an initially normal liver/spleen scintigram and benign hospital course. Twenty-three days after the trauma, the patient developed an acute abdominal crisis that brought him to the emergency room where an emergency ultrasound revealed hemoperitoneum and a subcapsular hematoma. At laparotomy, a splenic rupture was found. A splenectomy was not performed. Postoperative liver/spleen scintigram showed a persistent defect which was not present on the initial liver/ spleen scintigram.
