摘要:

A case of greatly increased blood flow in the region of a fracture with malunion of the left femur, both in the flow and immediate blood pool studies during three phase bone imaging, is presented. The sluggish left femoral artery flow resulted from the greatly increased regional perfusion and is similar to the findings in acute osteomyelitis. The sluggish left femoral artery flow and greatly increased regional perfusion of the site is probably best explained as a regional “neurovascular flush” resulting from the pain caused by the malunion of the fracture and/or hyperemia in the area of the malunion responding to inflammation.

摘要:

Eosinophilic pneumonia is usually diagnosed based on the findings on chest x-ray, white blood count, and transbronchial biopsy. After reporting a case of Ga-67 lung uptake in eosinophilic pneumonia, its histopathology is discussed and the mechanisms of Ga-67 uptake by inflammatory lesions are reviewed.

摘要:

A case of multifocal avascular necrosis of the bone complicating systemic lupus erythematosis is presented in which the extent of involvement was incidentally identified by Tc-99m HMPAO leukocyte imaging. Leukocytes labeled with Tc-99m HMPAO may be an excellent bone marrow imaging agent.

摘要:

I-131 metaiodobenzylguanidine (MIBG) imaging was performed in 38 patients with advanced neuroblastoma. Abnormal images were found in patients with elevations of urinary vanillylmandelic acid and dopamine and high serum neuron-specific enolase levels. Normal or minimal elevation of markers was seen in patients with negative images. In follow-up studies after chemotherapy, the disappearance of abnormal uptake was noted in those patients with normal marker values. A persistently abnormal uptake occurred in patients with high marker values. Conversion from a normal image to an abnormal image also occurred in patients whose markers became elevated. I-131 MIBG imaging is sensitive in detecting active foci of a neuroblastoma and is useful in monitoring chemotherapy in these patients.

摘要:

A gastrointestinal (Gl) bleeding scan was performed using the modified in vivo Tc-99m red cell labeling technique. Images were obtained at frequent intervals to localize the bleeding site on a 77-year-old patient with recurrent episodes of gastrointestinal hemorrhage. The patient had a left colon resection and anastomosis for diverticulitis 3 months before this study. During imaging, the bleeding site was detected in the lower descending colon. Retrograde flow was noted on the image (after a bowel movement) in the right colon but the pattern at this distal site was not related to an additional bleeding source at surgery. Surgical findings revealed the bleeding point at 5 cm above the previous anastomosis in the sigmoid colon.

摘要:

Meningocele and myelomeningocele are two of the more common abnormalities of the spinal cord and meninges. They occur because of herniation of distended meninges through a dysraphic spine. Approximately 70% are below the level of L2. The pathogenesis of rachischisis is unknown. They are frequently associated with abnormalities of the gastrointestinal and genitourinary systems. Sixty to 90% of the patients have hydrocephalus. A large photon-deficient right upper quadrant mass was discovered in a 6-month-old infant who had Tc-99m glucoheptonate renal imaging. Computed tomography demonstrated a large meningocele. Meningocele should be included in the differential diagnosis of photon-deficient masses seen with glucoheptonate renal imaging.

摘要:

A para-aortic hematoma was detected with ln-111 labeled leukocytes in a 28-year-old black man with a history of severe collagen vascular disease, who had a translumbar angiogram for evaluation of a right iliac artery pseudoaneurysm. Clinically the patient developed back pain and discoloration around the puncture site. This case demonstrates another instance of disposition of labeled leukocytes in sites other than foci of infection.

摘要:

Bone imaging of a patient with carcinoma of the prostate showed increased radioactivity in the right shoulder. He had become an enthusiastic shotgun hunter several years earlier. The hot spot was most likely related to damage caused by the impact of the rifle butt on the right shoulder during shooting.
