Diskography: infectious complications from a series of 12,634 cases.

BACKGROUND AND PURPOSE: Diskography is commonly performed to investigate pain of suspected diskogenic origin. Although uncommon, diskitis is a feared complication of this procedure. We reviewed the incidence of diskitis and other infectious complications following diskography in a large busy outpatient practice and discuss technical aspects that may contribute to infection prevention. METHODS: We reviewed the electronic records of all diskograms obtained at our institution during a 12.25-year period, looking for all cases of procedure-related infection. All diskograms had been obtained by skilled and experienced procedural radiologists in dedicated spine-injection suites with specialized technical staff. RESULTS: There were 12,634 examinations performed on 10,663 patients for a total of 37,135 disk levels. Of the disk levels, 5981 were cervical; 3083, thoracic; and 28,071, lumbar. Two cases of confirmed lumbar diskitis and no cases of either cervical or thoracic diskitis were seen in our series. No other infectious complications were found. The incidence of diskitis was 0.016% per examination and 0.0054% per disk level. CONCLUSION: In skilled and experienced hands using proper technique, diskography is a safe outpatient procedure with an extremely low incidence of diskitis and other procedure-related infections.

Nasojejunal feeding tube placement in children: four-year cumulative experience.

PURPOSE: Experience with fluoroscopically guided nasojejunal feeding tube placement in children was assessed regarding clinical diagnosis, fluoroscopy time, radiation dose, success rate, and placement failures. MATERIALS AND METHODS: From 1987 to 1991, 562 nasojejunal tubes were placed in 232 patients aged 1 week to 24 years (mean, 3 1/2 years) at the authors' institution. In every case, an 8-F feeding tube system was inserted. The fluoroscopy times and tube placement positions were evaluated in all cases. RESULTS: The mean fluoroscopy time was 5 minutes 30 seconds, which corresponded to an estimated mean midline fluoroscopy dose of 0.32 cGy. The tube was placed at or distal to the duodenojejunal junction in 543 attempts, for a success rate of 97%. The most common cause for unsuccessful tube placement was malrotation, with the fluoroscopic time and radiation dose significantly (P < .001) prolonged in these cases. CONCLUSION: Fluoroscopic guidance of placement of nasojejunal feeding tubes in children is successful, but the radiation exposure is not negligible and must be weighed against the need for nasojejunal feeding.

Imaging the testis: comparison between MR imaging and US.

The potential role of magnetic resonance (MR) imaging in the diagnosis and local staging of testicular tumors was evaluated in 23 patients who subsequently underwent surgery or biopsy. Findings at MR imaging were compared with those at ultrasonography (US) and were correlated with the surgical-histologic findings. At surgery, three patients were found to have extratesticular and 20 patients intratesticular abnormalities. This distinction had been correctly made with both imaging modalities, but US did not demonstrate the intratesticular abnormality in four patients with diffuse infiltrating tumors. Neither modality allowed differentiation of benign from malignant disorders. When local tumor staging was analyzed in 11 patients, the accuracy of both modalities was disappointing (true-positive findings with MR imaging in seven patients and with US in five). At present, US remains the primary imaging modality for testicular disease. MR imaging should be employed when findings at physical examination and US are discrepant and considered when diffuse infiltrative disease is suspected.
