Prospective comparison of magnetic resonance sialography and digital subtraction sialography.
We sought to compare the diagnostic utility of magnetic resonance sialography (MRS) and digital subtraction sialography (DSS) in patients with suspected sialolithiasis or sialadenitis. Sixteen consecutive patients (4 female and 12 male, mean age 51+/-16 years) with suspected sialolithiasis or sialadenitis underwent DSS by a standard technique and MRS. MRS was obtained with a T2-weighted single-...
متن کاملEffectiveness of the single‐shot dual‐energy subtraction technique for portal images
The aim of the present study was to evaluate the clinical efficacy of the single-shot dual-energy subtraction technique for obtaining portal images. We prepared two storage phosphor plates for this study. A 1 mm thick tungsten sheet was placed between the two storage phosphor plates. A single use of the double-exposure technique provides two portal images simultaneously (i.e., a standard image ...
متن کاملSingle-shot dual-energy subtraction mammography with electronic spectrum splitting: feasibility.
We present a single-shot dual-energy subtraction mammography technique using an energy sensitive photon counting detector. An electronic threshold near the middle of the X-ray spectrum discriminates between high- and low-energy photons, and allows the simultaneous acquisition of high- and low-energy images which can be combined to suppress anatomical clutter. By setting the electronic threshold...
متن کاملThe clinical utility of a one-shot energy subtraction method for thoracic spine radiography.
BACKGROUND The interpretation of thoracic spine X-rays is difficult because these images cannot clearly visualize the thoracic spine because of the overlap with soft tissues, such as the heart and pulmonary blood vessels. Thus, to improve the clarity of thoracic spine radiographs using existing radiograph equipment, we have investigated a one-shot energy subtraction method to visualize thoracic...
متن کاملComparative study of MR sialography and digital subtraction sialography for benign salivary gland disorders.
BACKGROUND AND PURPOSE MR sialography has become an alternative imaging technique for ductal salivary gland diseases. We compared the diagnostic accuracies of MR sialography and digital subtraction sialography in patients with successful completion of both examinations and benign salivary gland disorders. METHODS In a prospective study, we attempted to examine salivary glands in 80 patients w...
