Abstract

This article reveals a clinical case dedicated to a young woman, professional athlete, who made an appointment at NN Blokhin Russian Cancer Research Center for differential diagnostics of left tibia bone lesion, diagnosed by local health facilities. There were no patient complaints during routine check-up. Oncologist made an appointment for bone scan and second opinion on CT scan (was also made). Incidental findings on scintigraphy required further investigation. So a decision to perform a hybrid SPECT/CT of pelvis, MRI of pelvis and left talocrural joint was made. After complete examination non-osteogenic fibroma of left tibia bone was set as diagnose. Also there were several unexpected findings such as stress fracture of the navicular bone of the left foot, prevalent fracture of the left ischium without signs of consolidation and with the formation (developing) of a false joint and heterotopic ossification in soft tissues and ankylosis of the intervertebral joint L₅/S. This findings more likely to be posttraumatic complications.

Abstract

Slot-radiography is an x-ray examination in which a two-dimensional radiography with a straight beam and further computer stitching of the images obtained on the workstation during a single-pass of x-ray tube over a patient. The application of innovative techniques for image acquisition and processing in combination with a large-area flat panel detector (FPD) makes it possible to produce long-view images from one to several anatomical regions. During the investigation, the x-ray tube and the FPD move simultaneously at a constant speed in parallel relative to one another with the longitudinal axis of the body. Thus, it makes possible to obtain images with little distortion and processed images without visual defects. And this allows conducting more accurate diagnosis of pathological changes. Slot-radiography can be performed both in the patient’s standing position and lying down depending on the region of interest and tasks. It is possible to obtain images in both a frontal and a lateral projection without loss of quality.

Slot-radiography is effectively used to diagnose pathological changes in joints and spine, including scoliosis, limb shortening, segmental spinal instability, pathology of lower limb veins, and also as a method for assessing the quality of the treatment. This technique is characterized by safety and convenience for the patient: minimal time costs and low radiation exposure.

The application of this technique significantly increases the informative value of the x-ray examination, brings it to a qualitatively new level, providing a physician with a wide range of diagnostic possibilities.

Key words: slot radiography, digital radiography, flat panel detector, orthopedic surgery

Abstract

The article assesses the personnel situation in the field of domestic radiation therapy and nuclear medicine. Despite the fact that in recent years there has been a significant re-equipping of Russian medical centers with the latest devices, the quantitative indicators of medical equipment normalized for the number of residents of the country are still significantly inferior to the indexes other countries. And this problem is greatly aggravated by the insufficient number of specialists who can work on the equipment supplied. First and foremost, this refer to medical physicists who are responsible not only for ensuring the required accuracy when applying a dose of ionizing radiation to the tumor, but also for ensuring radiation safety when working with sources of ionizing radiation.

A continuing vocational educational retraining program covering development, operation and application of high-tech systems for radiotherapy is being proposed. This program was developed and tested at the Department of Physics of Accelerators and Radiation Medicine of the Physical Faculty of M.V. Lomonosov Moscow State University with the support of the Rusnano Foundation for Educational Programs.

The co-executors in the development and approbation of the Program were the National Medical Research Center of Radiology, A.I. Burnasyan Federal Medical Biophysical Center of the FMBA of Russia. Invited experts in the process of developing the Program were scientists and specialists of the Bauman MSTU, Tomsk Polytechnic University, NRNU MEPhI, N.N. Blokhin National Medical Research Center of Oncology. As a result of a professional educational program, the necessary professional skills for working as specialists in radiotherapy units and nuclear medicine centers are formed, which will successfully solve the problem of professional human resources for the clinical centers of Russia.

The program was developed and successfully implemented at the Department of Physics of Accelerators and Radiation Medicine of the Physics Department of M.V. Lomonosov Moscow State University.

The need to develop a program of assessment of medical physicists, which are working at the moment, is being considered. This will guarantee a high level of knowledge necessary for full participation in the medical process and making responsible decisions on the therapeutic use of radiation devices and ensuring radiation safety of patients and personnel.

Key words: medical physics, nuclear medicine, radiotherapy, retraining of specialists, the system of assessment of medical physicists
