[The clinical x-ray diagnosis of pulmonary hamartomas]. / Kliniko-rentgenologicheskaia diagnostika gamartom legkikh.

A clinico-roentgenologic study of 67 patients with hamartoma of the lung was carried out. Hamartoma could not be even suggested unless X-ray examination was performed but even this procedure sometimes failed to identify the disease. It was far from being each case that typical roentgenologic features of hamartoma were observed. Transthoracic needle biopsy may be helpful in identifying the nature of a roentgenologically detected tumor. Roentgenologically, hamartoma should be first of all distinguished from peripheral lung cancer. When clinico-roentgenologic and needle biopsy data are inconclusive with respect to lung cancer diagnostic thoracotomy should be performed.

[X-ray diagnosis of complications of purulent processes in the wrist]. / K rentgenodiagnostike oslozhnenii gnoinykh protsessov kisti.

To reveal the spreading of a purulent process to the antebrachial fatty spaces a study was made of an x-ray picture of soft tissues of the radiocarpal articulation and the forearm distal half in 126 patients with hand paronychia and phlegmon. In 24 of 95 patients with an unclear clinical picture of purulent discharge, typical x-ray symptoms of changes in soft tissues of the distal third of the forearm were found: typical deformity of fatty spaces with its distinct dynamics with relation to a stage of development of a pathological process. X-ray investigation permits the recognition of complications in hand purulent processes in order to take necessary therapeutic measures.

[Electroroentgenography in the diagnosis of soft tissue tumors]. / Elektrorentgenografiia v diagnostike opukholei miagkikh tkanei.

Clinical, electroroentgenographic and X-ray studies of soft tissues were carried out in 425 patients with malignant (75), benign (246) soft tissue tumors and in cases of such soft tissue pathologies of the extremities and body (104) as bursitis, hematoma, cyst and ganglia which may clinically simulate tumors. The paper discusses the technicalities of electroroentgenography which produces on one roentgenogram separate images of all components of soft tissues and bones in a given segment. A comparison of image quality assured by electroroentgeno- and roentgenography did not establish any significant difference in soft tissue tumor semiotics. Electroroentgenography of soft tissues is relatively less sophisticated, time-consuming and cheaper; it does not require special medical facilities for examining patients bearing soft tissue tumor or suspect lesions.

[Use of large-frame fluorography in the diagnosis of stomach cancer]. / O primenenii krupnokadrovoi fliuorografii v diagnostike raka zheludka.

A comparison of the results of non-aimed large-frame fluorography (LFF) and roentgen study of the stomach in 301 patients enabled ascertaining more precisely the opportunities of LFF in diagnosing gastric cancer. It was found by checking (fibrogastroscopy with biopsy or surger) that irrespective of the technic of non-aimed LFF, despite the diagnosis being known previously, cancer of the stomach still far from being in early stage may be recognized only in 62-63%. Therefore use of non-aimed LFF to diagnose gastric cancer during mass prophylactic examinations seems to be not rational.

[Clinical x-ray and fibergastroscopic comparisons in the diagnosis of different forms of stomach cancer growth]. / Kliniko-rentgenologichekie i fibrogastroskopicheskie sopostavleniia v dianostike razlichnykh form rosta raka zheludka.

A radiological examination associated with fibergastroscopy was performed in 145 gastric cancer patients. All these patients were radically operated upon--extremely subtotal resection of the stomach was accomplished. The preoperative diagnosis of gastric cancer with both technics used simultaneously proved to be correct in 96.55%. However, the anatomical and ulcerous-infiltrative growth, especially in their cardiac and subcardiac localization are found to present the greatest diagnostic difficulties. The data obtained made it possible to believe that the detailed diagnosis of gastric cancer should comprise two steps--a radiological examination and fibergastroscopy.
