Abstract:

We have performed a comparative analysis of magnetic resonance mammography (MRM) and traditional methods of diagnostics in detection of multifocal and multicentric kinds of breast cancer (BC) growth in 21 patients with difficult anatomy structure of mammary gland (MG) Breast-conserving surgery has been already planned for all these patients

Complex diagnostics included ultrasound(US), X-ray mammography (XRM), MRM with contrast enhancement, diagnostic needle biopsy Minimal size of identified breast tumors on the base of XRM data was 7 mm, ultrasound - 4 mm, at MR mammography - 2 mm XRM and US have detected multifocal tumor growth only in 1 case (5%). MRM revealed multifocal and multicentric tumor growth in 9 (43%) and 4 (19%) patients respectively According to revealed data the volume of surgical treatment has changed: 10 patients (48%) underwent radical resection, 10 (48%) mastectomy and 1 (5%) - partial resection

According to the conducted research it has been revealed that preoperative MR mammography is necessary for treatment planning in patients with breast cancer to avoid cancer recurrence after breast-conserving surgery.

Abstract:

Purpose. Was to reveal atypical MRI-signs of leiomyomas.

Materials and methods. Kinds of degeneration: hyaline (60%), cystous (4%), hemorrhagic and myxomatous. In rare case of 8% myomas can be localized in uterine cervix and its surrounding structure - ligamentum uteri latus, vagina and retroperitoneal area. Connection between uterine and myomatic node can be lost due to torsion and necrosis. Such situation leads to wrong diadnosis ((retroperitoneal tumor with extraorganic localization*. Such tumors displace bladder, rectum and descending colon to the front. Due to surrounding fabrics pressure these tumors have irregular forms. Atypical myomas with extrauterine localization often have cystoid degeneration, necrosis and hemorrahages - such situation needs differential diagnostics firstly with leiomyosarcomas: these malignant newgrowth more often than simple leiomyomas have such localization and structure.

Discussion. We have described two cases of leiomyomas atypical localizations, which had been estimated as an extraorganic tumors during diagnostics' initial stages. It is very important to differentiate leiomyomas from other tumors of the same localization. In case of cancer-tumors - immediate surgical treatment is necessary

Conclusions. Histological structure and clinical current knowledge can help to differentiate this tumor with atypical signs from malignant gynecological new growth. MRI can be used in diagnostics of atypical leiomyomas.

Abstract:

Purpose. Was to investigate the radiodiagnostic features of ASD in different age groups and to evaluate the role of chest X-rays in diagnostics of this disease.

Materials and methods. 48 patients with ASD were studied (aged 15–71 yaers, mean 47,2 ± 15), including 16 men and 32 women. We have diagnosed ostium primum defect (3 pts), ostium secundum defect (42 pts), sinus venosus defect, combined with PAPVD (3 pts). All of them underwent chest x-rays, echocardiography and cardiac MRI (with phase-contrast sequences). Patients were divided into two groups: 1st group – older than 40 years (30 pts) and 2nd group – less than 40 years (18 pts).

Results. In the 1st group, heart failure, valve regurgitations and atypical radiographic findings were more common than in the 2nd group. The size of both atria, pulmonary arteries' diameter and systolic PAP levels were also greater in patients older than 40 yaers. Groups did not differ by the volume of intracardiac shunt and the size of the defect. 6 pts with small defects had no radiographical signs of CHD. 11 patients from the 1st group had signs of hypervolemic CHD, but significant heart chambers’ enlargement impeded more accurate diagnostics. Patients with marked pulmonary arterial hypertension differed significantly from patients with lower PAP levels by radiographical signs.

Conclusions. Specificity of chest x-rays in diagnostics of ASD is lower in patients of 2nd group. Chest x-rays is an effective screening method to reveal abnormalities of pulmonary circulation, such as pulmonary venous hypertension and pulmonary plethora.

Abstract:

Purpose. Was to compare beam loading and quality of coronary arteries’ imaging (CA) in case of using the 64-lise computed tomography (MSCT) in retro-and prospective electrocardiographic synchronization mode.

Materials and methods. 57 patients with coronar arteries disease suspicious were examined with the help of computed tomography (CT) coronarography in prospective (n = 27) and retrospective (n = 30) EKG-synchronization modes. All the experiments were held on multislice Discovery CT 750 MD («General Electric»). The quality of obtained CR images was estimated subjectively – from 1 (perfect quality) to 4 (non-

diagnostic).

Results. The analyses of obtained images during retro-and prospective EKG-synchronization did not reveal serious differences (1,4 ± 0,38

and 1,5 ± 0,46 accordingly). The effective dose during prospective EKG-synchronization was 59% less than during retrospective EKG-synchronization (3,8 ± 0,83 mSv and 9,3 ± 2,5 mSv, р < 0,05).

Conclusion. CT-coronarography in prospective EKG-synchronization mode leads to essential decrease in beam loading on the patient without deterioration of the received image quality.

Abstract:

Purpose. Was to investigate the role of diffusion weighted imaging (DWI) in focal hepatic lesions diagnostic.

Material and methods. Data of 70 patients (20 men) aged 28-78 years with focal hepatic lesions were analyzed. All of them underwent 1,5 T MRI; DWI obtained at b values of 50 s/mm2, 400 s/mm2, and 800 s/mm2. The results of MSCT data, intra-operative visual and ultrasound examination, histology of operation probes, and follow-up data were confermed.

Results. In 70 patients 203 focal lesions sized 3-168 mm: cysts (55), angiomas(36), metastases (89), nodal hyperplasia(5), primary tumors (5), abscesses (5), focal necroses (2) were revealed. DWI is capable of making differential diagnosis of focal hepatic lesions: cysts were not visualized at b = 800 s/mm2, and their ADC was (2,5 ± 0,2) × 10~3 s/mm2. Metastases were visible in all b-values, and had ADC lower than that for cysts (1,2 ± 0,5) × 10~3 s/mm2). Angiomas also were good visualized in all b-values, but ADC of angiomas was higher and varied from 1,5x 10~3 to 2,6 x 10~3 s/mm2. DWI is advantageous in detecting of small (less than 1 cm) foci: even if this kind of lesions was indistinct atT1 and T2 weighed images, DWI showed high intensity and well-defined edges.

Conclusions. Diffusion weighed MRI appeared to play additional role in differential diagnosis of focal hepatic lesions, enhancing detectabi-lity of the small (less than 1 cm) foci. The technique is simple, cost-effective and not time-consuming.
