摘要:

A dynamic renal study revealed an immediate blush in the bladder region. This was not uterine related (previous hysterectomy). The outline of the site did not change with time as bladder filling progressed. The effect was due to a bladder relatively fixed in shape from the late effects of radiation, with probable continued vascular abnormalities within its walls.

摘要:

Two diabetic patients with cellulitis and surgically proven gangrene of the toes were evaluated with combined Tc-99m MDP bone scans and In-111 WBC scans. The bone scans showed unusual "cold" areas in the area of the gangrene. The WBC scans were positive in both cases. In each case, the imaging technique was to label the patients WBCs with 500 µCi of In-111. The next day, a three-phase bone scan was performed using a medium-energy collimator and dual-isotope imaging. This procedure allows precise overlapping of the Tc-99m MDP bone and In-111 WBC images. In each of these cases, the bone tracer was unable to localize in the gangrenous area because of the impairment to blood flow. The WBCs, which had the advantages of a) 24 hours to localize, and b) the fact that WBCs can move outside of vascular channels, were able to identify the infection.

摘要:

The authors present a case of extrapulmonary Tc-99m macroaggregated albumin uptake in a patient with reversed atrial septal defect and cleft lip. Perfusion lung scanning was performed to rule out pulmonary embolism because of dyspnea, cyanosis, and tachy-arrhythmia. Besides minimal systemic activity, significant myocardial uptake of the tracer was observed. Coronary angiography could not be performed because of the severely altered general condition of the patient. It was postulated that this was most probably due to an anomalous origin of the left coronary artery from the pulmonary trunk.

摘要:

Sweat gland carcinoma is a rare malignancy of the skin with a poor prognosis. The principal mode of therapy has been local surgical excision, which may be supplemented by adjuvant chemotherapy and radiotherapy. More than 50% of patients develop either local tumor recurrence or regional lymph node metastases after surgery. The authors report a case of sweat gland carcinoma in which recurrence was detected by F-18 FDG PET imaging. FDG PET imaging can be helpful in early detection of local recurrence.

摘要:

A 59-year-old man had radiation therapy for rectal carcinoma. Because of ensuing bowel problems and poor nutritional intake, he was referred for a bone densitometry examination. The lumbar area revealed massive uptake adjacent to and behind the vertebral column. This proved to be an intraabdominal abscess. The aberrant collection was no longer noticeable after drainage of the abscess.

摘要:

Increased thoracic radioactivity on bone imaging was found to be due to tracer activity in a central venous catheter. Continuous flushing of the catheter caused the artifact to disappear partially.

摘要:

Bellini duct carcinoma is a very rare disease originating from the collecting tubules of the kidney. Ga-67 imaging was performed in a patient who had primary malignancy in the left kidney and worked every metastases. Ga-67 uptake was seen in both the primary neoplasm and metastases. The tumor was found to be a Bellini duct carcinoma.

摘要:

Avascular bone necrosis is a serious complication in patients with systemic lupus erythematosus (SLE). The femoral heads are the most frequent necrosis sites. Although its pathogenesis still remains unclear, abnormal hemostatic states and the young age of patients with SLE have previously been proposed as risk factors. It is also well known that corticosteroids are a major osteonecrosis inducing factor. The authors report the case of a 25-year-old woman who was diagnosed with SLE 4 years earlier, and who had hemolytic anemia. She had been treated with corticosteroids, had bilateral hip pain for 3 months, and pain in the left shoulder and right knee for 1 month.

摘要:

A 50-year-old woman had a history of cervical carcinoma(stage 1B) since 1991. She underwent transabdominal hysterectomy with pelvic lymph node dissection. Five years later, she presented with a right renal obstruction. A renal scan performed to evaluate the right renal function showed minimal function in the right kidney, but revealed a hypervascular mass with retention of DTPA (retention index of 2.62). MRI of the abdomen and pelvis revealed a low-signal mass in the pelvis and an MR urogram showed a right hydroureter and hydronephrosis. A bone scan was obtained to exclude osseous metastases and showed intense uptake in the region of the right sacroiliac (SI) joint. A CT guided biopsy of this region revealed recurrent cervical carcinoma. The patient received radiation therapy to the right pelvic area.
