[Small pelvic MRI on "Ellipse" low-adz tomograph made in Russia].

The paper presents the authors' experience in using small pelvic MRI on an Ellipse low-field apparatus made in Russia. A total of 74 patients were examined. Abnormal formations in the small pelvic organs were visualized in 72 patients.

[Oncogenic osteomalacia: its pathogenesis, clinical picture and treatment].

A female of 53 and male of 35 complained of myasthenia and pain in the bones. Biochemically, they had severe hypophosphatemia secondary to a sharp decline in tubular reabsorption of phosphates. X-ray showed tumor of bone tissue.

[Magnetic resonance tomography in the diagnosis of intramedullary tumors].

The data of magnetic resonance imaging in 23 patients is hardly sufficient to characterize the histologic types of intramedullary tumors. However, the presence of cystous type of structure of intramedullary tumors on magnetic tomograms with nonhomogeneous (iso- or hypointensive) signal on T1-suspended tomograms or of hyper- or hypointensive signal on T2-suspended ones is to a great measure indicative of infiltration and diffuse growth of a tumor. A solid structure of intramedullary tumor with homogenous hyperintensive signals on both T1- and T2-dependent tomograms is more frequently indicative of a slowly growing tumor not involving the medulla, e.

[Pathological restructuring of compact bone tissue as evidenced by detailed x-rays of hands].

The author analyzes precise roentgenograms of the hands in more than 250 patients with diseases of the skeleton, resultant from dysmetabolism. He emphasizes the similarity between juxta-endosteal and intracortical resorption of compact bone tissue at some sites of the compact matter. Three degrees of intracortical resorption are distinguished and its relationship to the blood parathyroid hormone level revealed.

[Irreversible loss of the substantia compacta in metabolic bone diseases based on roentgenogrammetric data].

A study was made of gram roentgenographic indices of the compact substance (CS) in metabolic skeletal diseases: of the cortical layer summary thickness (CST) and a cortical area (CA) of the metacarpal bone II in 310 patients and the femoral cortical index (FCI) in 184 patients. Three components in CS loss were singled out: involution, metabolic and inert. Irreversibility of endocortical loss of the osseous tissue was shown and interpreted as fast developing involution osteoporosis.

[Clinico-roentgenologic characteristics of postoperative osteitis of the pubic bones].

The paper is concerned with clinicoroentgenological analysis of postoperative osteitis of the pubic bones (OPB) in 29 patients with urological diseases. The development of OPB follows operative complications, mainly of pyoinflammatory type. Clinically OPB develops as a pyoinfectious process.
