[Comparative characteristics of radiation imaging methods in the diagnosis of sacroiliitis].

Patients with sacroiliac joint, injuries, ankylosing spondyloarthritis, or spondyloarthropathy of various genesis were examined. Pelvis x-ray, spiral computed tomography (CT), and magnetic resonance imaging (MRI) were performed. MRI was found to have advantages in the detection and evaluation of the pattern of detectable bone changes. It is inexpedient to use traditional x-ray study and CT for the detection of edematous-infiltrative changes in both osseous and fibrous and soft tissue elements of the joint since the sensitivity of these techniques is insufficient to detect. To analyze detectable changes, it is expedient to use a unified MRI protocol that involves the characteristics of osseous, fibrous, and soft tissue structures of the joint.

[The role of low-field strength magnetic resonance imaging in bladder cancer staging].

This article shows the role of magnetic resonance imaging (MRI) in complex diagnostics of urinary bladder cancer. The paper analyzes the authors' own data of urinary bladder MRI in 40 patients with histologically proven bladder cancer. This study demonstrates the additional capacities of low-field strength MRI with enhanced technique including conventional T1-, T2-weighted images along with FLAIR and PD images.

[A rare case of metastases in the diaphragm in a patient with gastric cancer].

In spite of the general affection of the greater curvature of the stomach, there were no dyspeptic manifestations, pains in the upper half of the stomach were not related to meals, 'and the stool remained unchanged. The main characteristic of the clinical picture was the distribution of the tumor process to the diaphragm, which was a reason explaining the complaints about acute pains in the right flank enhancing in the course of movements or deep breaths. No data about any metastatic affection of the skeleton bones, lungs or pleura were received. This case shows the need in the close examination of the diaphragm in the case of the pain syndrome in the right hypochondrium in patients with generalized tumor diseases.

[Ultrasonography and magnetic resonance imaging in diagnosing recurrent and metastatic ovarian cancer].

The paper deals with the capacities of ultrasonography (USG) and magnetic resonance imaging (MRI) in diagnosing recurrent and metastatic ovarian cancer along with routine clinical and laboratory studies (physical examination, measurement of the tumor-associated serum antigen CA-125) in 95 patients with ovarian cancer after primary special treatment. MRI is preferable to USG in evaluating the extent of a tumorous process and the invasion of a tumor into the adjacent tissues, which is of great value in defining a further treatment policy.

[Magnetic resonance imaging (MRI) in the diagnosis of recurrences of ovarian cancer in the small pelvis].

The paper provides the results of small pelvic magnetic resonance tomography (MRI) in 62 patients with ovarian cancer after primary special treatment. Out of them 50 patients were found to have recurrences and metastases of the underlying disease, 12 patients had clinical remission. The study yielded MR signs and MR semiotics of recurrences of ovarian cancer in the small pelvis. The capacities of MRI with low and high intensities of a magnetic field were comparatively studied in the diagnosis of recurrences and metastases of ovarian cancer.

[Standardizing a protocol of magnetic resonance imaging of temporomandibular joints. Part I]. / Standartizatsiia protokola magnitno-rezonansnoi tomografii visochno-nizhnecheliustnykh sustavov. Chast' I...

The paper presents the standard of a procedure for magnetic resonance imaging of temporomandibular joints, which has been used to examine 275 patients. It describes the study projections, that are most significant for visualization, and scanning protocols. Illustrations of magnetic resonance imaging of the structures of the intact temporomandibular joint are presented.

[Standardizing a protocol of magnetic resonance imaging of temporomandibular joints. Part 2. Unification of analysis of obtained data]. / Standartizatsiia protokola magnitno-rezonansnoi tomografii visochno-nizhnecheliustnykh sustavov. Chast' 2. Unifikatsiia analiza poluchaemykh dannykh.

The paper presents a unified protocol for analyzing the data obtained by magnetic resonance tomography, which has been used to examine 350 patients. It characterizes the MR semiotics of different pathological conditions of articular structures, which are illustrated by MR images. An optimal terminology is proposed for the evaluation of bone and soft tissue changes.

[Spiral computed tomography in the diagnosis of limb osteomyelitis]. / Spiral'naia komp'iuternaia tomografiia v diagnostike osteomielita konechnostei.

The results of radiation studies in 121 patients of different age (4 to 75 years) examined for limb osteomyelitis are analyzed. All the patients underwent routine X-ray study and computed tomography (CT), 26 patients had X-ray fistulography; 8, linear tomography; 10, CT fistulography; 6, scintigraphy, and 15, ultrasound study. Acute hematogenous osteomyelitis (AHO), chronic hematogenous osteomyelitis (CHO), and atypical (here Garre's sclerosing osteomyelitis and Brodie's abscess) osteomyelitis were ascertained in 10.6, 26.4, and 10.1% of cases, respectively. Posttraumatic osteomyelitis was diagnosed in almost 50% of the patients. CT defined the phase of chronic limb osteomyelitis. Spiral CT has proven to be the most effective technique for diagnosing limb osteomyelitis as compared with routine X-ray study: the accuracy of X-ray study was 81.8%, its sensitivity, 84.9%, and specificity, 60.0% and those of computed tomography were 96.7, 99.1, and 80.0%, respectively.

[Prognostic significance of helical CT in patients with destructive pancreatitis]. / Prognosticheskaia znachimost' dannykh rentgenovskoi spiral'noi komp'iuternoi tomografii pri destruktivnykh pankreatitakh.

Spiral scanning computed tomography (CT) is able not only to image the pancreas and to evaluate its structure, but to interpret the status of the adjacent organs and tissues. CT symptoms of pancreatic necrotic changes and multiorgan failure were studied in the prospective follow-up of 47 patients with prior destructive pancreatitis (158 studies). CT differentially substantiated indications for choosing treatment policy for different forms of pancreatic lesions. The paper gives a quantitative assessment of necrotic pancreatic parencymatous areas and shows its prognostic value.
