[INTRODUCTION - Tarsal coalition is an abnormal bony, cartilaginous or fibrous union between two or three bones of the mid and hindfoot. It occurs mostly (90%) in the calcaneonavicular and talocalcaneal joints. Coalitions are usually detected in the second decade of life, but several cases are noted in children and in later adulthood. Estimated incidence is 1-2% of the total population. CASE REPORTS - Cases of unilateral tarsal coalitions (five calcaneonavicular, three talocalcaneal) in four male and three female patients are presented. The average age of the patients is 30 years. The radiologic diagnosis was based on the secondary signs seen on the lateral plain films of the feet. These signs are parallel with clinical symptoms, in contrary to the primary radiologic signs. The two types of the anomaly coexisted in a female patient. CONCLUSION - Routine lateral not-magnified pedal radiographs are valuable screening tool for tarsal coalitions.]

[INTRODUCTION - Modern radical radiotherapy can be an effective alternative of radical prostatectomy in low risk patients with prostate tumor. Our objective was to demonstrate the feasibility of transperineal MR-guided prostate interventions in an open MR unit and to present our early clinical experiences on canines. METHODS AND MATERIALS - The procedures were performed on 5 canines in an open-configuration 0.35T MR scanner. For interventions an MR compatible custom-made device was used. The canines were placed in the right lateral decubitus position. Template reconstruction, trajectory planning, target and OAR delineation were based on T2 FSE images. For image guidance and target confirmation, fast spoiled gradient-echo (FSPGR) sequence was used. MR compatible coaxial needles were inserted through the perineum to the base of the prostate. After satisfactory position was confirmed, brachytherapy catheters were placed through the coaxial needles, which were then removed. RESULTS - Mean and standard deviation of the needle displacements was 2.2 mm±1.2 mm, with a median of 2 mm. 96% of the errors were less than 4.0 mm. Implantation induced prostate motion was measured with a mean of 10.3 and 2.3 mm in cranio-caudal and transverse directions. Significant movement was only observed during the first 4 needle insertions. The average time needed for each step was: anesthesia 15 minutes, setup and positioning 15 minutes, initial imaging 15 minutes, template registration and projection 15 minutes, contouring, trajectory planning, insertion of 10 needles 60 minutes. CONCLUSION - Based on our canine model experiences our method seems to be a promising approach for performing feasible, accurate, reliable and high-quality prostate MR guidance within a reasonable time span. We plan to introduce MR-guided biopsy and brachytherapy in human patients in the near future.]

[Radioguided localization of the non-palpable breast lesions and sentinel lymph nodes]

MONOKI Erzsébet, VARGA Erika, SZABÓ Tünde, TARJÁN Tibor, PETRI István, ZS. TÓTH Endre, BAGDI Enikő, KRENÁCS László

[INTRODUCTION - As the result of mammographic screening of breast cancer, the incidence of surgically removable, non-palpable breast lesions is increasing. The study is aimed to demonstrate the use of radioisotope and gamma-probe for identifying the sentinel lymph node and the intraoperative radioguided localization of occult breast lesions. PATIENTS AND METHODS - 26 patients with nonpalpable breast lesions underwent radioisotope guided sentinel lymh node localization for staging purposes. In eight patients non-palpable breast lesions were localized with use of radioisotope method intraoperatively. RESULTS - All breast lesions were successfully localized pre- and intraoperatively. The combined radioisotope and blue-dye staining method increased the sensitivity of the procedure for identifying sentinel lypmh node. In case of 14 patients with negative sentinel node, the surgical dissection of axillary lymph nodes was avoided. CONCLUSION - Radioguided localization is a simple, quick and accurate technique for localization of nonpalpable breast lesions and sentinel lymph node, which is utilized for the up-to-date and correct oncological management of the breast cancer patients.]

[Changes in the approach and the methods in acute surgical treatment of severe thoraco-lumbar spinal injuries]

ZSOLCZAI Sándor, PENTELÉNYI Tamás

[The authors show the changes in the approach and methods concerning the acute surgical treatment of severe thoracolumbar spinal injuries. In the past 15 years, 878 acute surgical treatments have been done with ventral-, dorsal or combined method. The results are evaluated from the point of view of neurological function recovery, bony union, restoration of patients' comfort and complications. Authors discuss the changes of past 15 years regarding the basic ideas of the treatment of spinal injuries, the indications and methods of modern surgical techniques. The use of new surgical methods which are closely connected to the biomechanical characteristics of the injured spine are stressed, as well as the importance of the primary definitive ventral surgical treatment, in the case of a severe thoraco-lumbar spine injury.]

[MAGNETIC RESONANCE IMAGING IN MUSCULOSKELETAL DIAGNOSTICS]

MESTER Ádám

[The aim of the author is present a practical MRI guideline for partners clinicians working in general or specialist patient care related to musculoskeletal diseases. The evidence based diagnostic decision-making process requires specific and realistic expectations related to MRI in daily practice. The focus message of the article is that the more exact and specific clinical question arrives, the more accurate and precise answer of the radiologist is achieved. The importance of detailed clinical information based optimal planning is emphasized versus “general” studies based on poor clinical information. It is not less important for the referring physician to prepare and inform the patient prior to the MRI study, with the exclusion criteria and contrast agent application all explained. Very few technical details are presented, only as little as possible to understand the clinically relevant properties of the imaging process.]
