One hundred and eighty-five breast cancers were demonstrated by xeroradiography in 6,238 patients. Sixty-two cancers were occult, and constituted one-third of the demonstrable breast cancers. Some of the patients with clinically nonpalpable carcinomas had high risk factors known to be associated with the development of breast cancer. The diagnosis was usually established and confirmed by wide excisional biopsy of the area containing the suspicious lesion. In some instances the lesion was localized preoperatively by xeroradiography using a technique of skin markings. Specimen xeroradiography was utilized if there were calcifications seen on the preoperative xeroradiograph. There was a significantly decreased incidence of axillary node metastases in the occult cases when compared to the dominant mass cases.

Various methods have been introduced for obtaining radiographs. Xeroradiography which is a method of imaging uses the xeroradiographic copying process to record images produced by diagnostic x-rays. It differs from halide film technique in that it involves neither wet chemical processing nor the use of dark room. Literature on this subject is scarce. After an initial promising beginning, this imaging method, once thought to hold the key to endodontic imaging, got stagnated. A revisit of this promising endodontic imaging system would therefore be appropriate. The purpose of this study was to review xeroradiographic technique as a roentgenographic imaging system.

Ten patients with inflammatory disease (rheumatoid arthritis, ankylosing spondylitis, Reiter's disease) or metabolic disease (gout, pseudogout, tendinous xanthomatosis) affecting the Achilles tendons are presented and discussed. Radiological lateral views of heel were obtained with xeroradiographic techniques, which permitted the recording on the same image of details of both bone and soft tissue and the evaluation and quantification of the changes in the Achilles tendons. Xeroradiography seems to be a very suitable radiological technique for routine use in the evaluation and follow up of rheumatic diseases of the foot.

A case report of manubriosternal joint (MSJ) dislocation in a rheumatoid patient with thoracic kyphosis is presented together with a review of the relevant literature. Variations in the anatomical nature of the MSJ between normal individuals are described. In 43% of the population its characteristics are noted to be such that it may be involved in rheumatoid arthritis (RA). A joint thus involved can be dislocated by forces generated by longstanding thoracic kyphosis and transmitted to the manubrium via the first rib. Xeroradiographs of the MSJ region in our patient showed dislocation of the joint in the upright position and its subsequent reduction on lying the patient flat. We suggest that this demonstrated reduction is secondary to the lessening of the thoracic kyphosis that occurs in the supine position. It is concluded that in RA MSJ dislocation is a function of thoracic kyphosis.

Some details of the physics of xeroradiography, and the bearing these have on films of the lung obtained by this technique, are discussed. In experiments designed to obtain useful films with a minimum of radiation exposure it was found that an exposure range of 10-30 mas at 200 kV at 1.35 m (4 1/2 ft) without a grid or air gap gave very satisfactory results. The positive model of development was considered to give more information than the negative mode. One hundred and fourteen miners who had been exposed to silica dust, asbestos dusts or both, were examined by this technique. The xeroradiographs were compared with silver halide films taken at 200 kV. The xeroradiographs were considered to be superior in several respects, especially in the delineation of vascular shadows, normal and abnormal linear opacities. Linear opacities in asbestos-exposed subjects were better shown on the xeroradiographs and were occasionally seen on these films when the 200 kV conventional film was entirely normal. Small rounded opacities of silicosis were very poorly shown on the xeroradiographs. Pleural thickening and pleural plaques may be very well demonstrated.

Measurement of the size of the suprapatellar pouch of the knee appears to be a simple, useful, objective, and reproducible assessment of synovitis of the knee. Changes in the apparent size of the suprapatellar pouch have been shown to correlate closely with the volume of synovial fluid aspirated from the knee and with changes in circumferential measurements. Aspiration of 20 ml of fluid will produce a change in size significant at the 1% level. Lateral xeroradiographs were used in this study, as soft-tissue planes are more closely defined on xeroradiographs than on standard radiographs.

Clinical Trial Comparative Study Randomized Controlled Trial
A pulsed ultrasound technique was shown to have a high degree of correlation with the established xeroradiographic method for the determination of dermal thickness both in normal skin and corticosteroid treated skin, although xeroradiography consistently gave a higher value than ultrasound. Using the pulsed ultrasound technique, an early onset of dermal thinning could be detected 2 days following treatment with creams containing 0.05% clobetasol propionate and 0.1% beta-methasone 17-valerate. The amount of dermal thinning produced by the clobetasol propionate preparation was significantly greater than that produced by cream base, clobetasone butyrate 0.05% cream and hydrocortisone 1% cream as determined by both techniques. The pulsed ultrasound technique is an accurate, noninvasive and safe method for determining dermal thickness.

Comparative Study
Comparable conventional x-rays had xeroradiographs were obtained of the hands of 22 patients with rheumatoid arthritis. Each metacarpophalangeal and proximal interphalangeal joint was scored for juxta-articular osteoporosis, erosions, loss of joint space, soft tissue thickening, joint deformity, and osteophytes on a 0-3 scale. For 10 hands the films were reported again after 3 months, and each technique was reproducible. Comparison between the 2 radiographic techniques showed that overall they gave similar results, although osteoporosis was reported more frequently on conventional x-rays, and loss of joint space and synovial thickening on xeroradiographs.
