Medical Imaging

The Medical Imaging department at "Tokuda Hospital Sofia" is multidisciplinary and includes in its activities the full range of imaging and diagnostic examinations. The department is equipped with modern equipment, including a full line of modalities - conventional X-ray machines osteodensitometer, orthopantomograph, modern ultrasound, equipped with probes for abdominal organs, soft tissues, mammary glands, endorectal and endovaginal ultrasound and transducers for conducting biopsies under ultrasound guidance, digital mammography with functions for stereotaxic biopsy, 64-detector computed tomography and magnetic resonance 1,5T.

The doctors working in the department are with recognized medical imaging specialties profiled in various sub-specialties such as emergency medical imaging, oncology, neuroradiology, gastrointestinal radiology, urogenital radiology, musculoskeletal radiology, thoracic radiology, cardiovascular radiology, mammology medical imaging, and pediatric imaging. The doctors at the medical imaging department work in compliance with the European standards for Good medical practice and implement a number of innovative research techniques in the different specialty areas.

The philosophy in the Medical imaging department at "Tokuda Hospital Sofia" is entirely oriented towards the patient. We take care of the patient as our primary task, each examination is interpreted by professional medical imaging specialist and the results are discussed together with the patient. Our goal is for every patient to leave the department with a prepared result or consulted when necessary.

All examinations conducted in the Medical imaging department at “Tokuda Hospital Sofia” are processed, distributed and archived using the PACS system that allows continuous access to previous examinations and conducting a comparative assessment. The organization of images and results storage is based on the principle of so-called "patient record", which contains all available information held in the department or images provided for consultation. All images can be remotely transmitted and consulted with reference centers aided by telemedicine.

The examinations and consultations in the Medical imaging department are performed after a predetermined appointment at the Medical imaging department (+359 2 403 49 20). Our registrars are well informed about the major indications and contraindications for conducting various types of imaging examinations and are ready to assist or provide timely consultation with a specialist when needed. Prerecorded appointment supports our idea of full assistance and saving time spent on examination. Depending on the complexity of the processing of the received images and medical analysis, the results are obtained within 2 to 24 hours. For those of you who would like to receive the examination documents, the result could be sent to a provided in advance address.

The Medical Imaging organizes special ultrasound examinations for early detection of urological diseases and malformations of the urinary system in children over 6 months of age. The diagnostic examinations are carried out in the general children's center with Tokuda direction # 0634 personal child's pediatrician or paid admission. The prerecorded appointment can be recorded at phone: +359 2 403 49 48.

X-ray methods 

Conventional X-ray diagnostics - method for preparing a two-dimensional image shade based on different degrees of attenuation of X-rays in various body structures. The main conventional methods are:

X-ray graphy - the X-ray passed through the tissues forms on the image converter (x-ray film) a two-dimensional stationary shade image of the human body structures.

X-ray spectroscopy - the image is displayed on the monitor screen with X-ray electronic converter and a television camera. This allows dynamic analysis of processes and pathological changes. 

Computer tomography - an X-ray method for detailed images of the anatomic slices aided by computer which processes the data set (numerical values) for the intensity of the passed X-ray radiation trough the tissues. The method combines the X-ray capabilities and computer technology and enables a consistent, cross-section slices of the human body organs.

Mammography - an X-ray medical imaging method for research and visualization of the structures constituting the breast.

Angiography - invasive method in which the diagnostic images are obtained by injecting of contrast material into the blood vessels through a catheters introduced into the vessel. It is the main method of treating various vessels stenosis or occlusions in the human body.

What are X-rays?

The X-rays are a type of electromagnetic radiation such as the light, the radio waves, the ultraviolet and infrared waves, but they have ionizing action. They do not affect the human senses – they are intangible – cannot be seen or heard, do not cause pain or warming.

What is the usage of the X-rays?

The X-rays are used in medicine mainly for diagnostics. By X-rays the doctors confirm or reject the hypothesis of a particular disease, track the development of the already proven disease and the treatment outcome. 

Is there a risk related with the use of X-rays?

In X-ray examinations small dosage of X-ray radiation is used, tens of thousands of times smaller than those that could cause skin burns or radiation disease. For comparison, the radiation dosage of chest X-ray is equivalent to the dosage that each passenger gets in a five hour's flight.

Can you get a diagnostic image without X-rays?

There are two methods of medical imaging that do not use ionizing radiation - ultrasound diagnosis (ultrasound) and magnetic resonance computer tomography. The final decision on the method of examination is taken by qualified physician, according to the clinical question for any given patient. Ultrasound diagnosis (ultrasonography) - a method for preparing a two-dimensional image by the reflection of ultrasound waves at the boundaries between biological structures. The resulting image can reflect the anatomical features, track the function of an organ or the speed of the blood.

Magnetic resonance diagnostics – a non-ionized method for obtaining a detailed image of the anatomic slices and functional information on the principle of the nuclear magnetic resonance phenomenon - resonance absorption of high-frequency electromagnetic field energy by the hydrogen nuclei in the tissues, located in a permanent magnetic field. Due to MRT are obtained two-dimensional images similar to CT as the method allows an excellent distinction of details in the structure of the various tissues.

Radiation Protection

The Medical Imaging department at "Tokuda Hospital Sofia" is entirely dedicated to radiation protection of the patient.

The availability of software (DoseWatch GEHC) automatic collection and analysis of dosimetric data allows optimal dose monitoring information about patients and constantly optimizing the professional practice.

The methods are based on the fundamental principle of radiation protection ALARA (As Low As Reasonably Achievable) – reducing the exposure to the reasonable minimum. The application of this principle and the high competence of the team are vital for reducing the exposure dosage, i.e. of the ionizing radiation harmful effects. The complex of organizational and physic-technical measures to reduce the exposure includes the selection of the type and parameters of the ionizing radiation source, as well as the equipment and the control of its position in order to obtain optimal diagnostic information.

We see and observe strictly regulated rules in examination of children and pregnant women, with the ultimate goal is to reduce the radiation risk and obtain the maximum possible benefit for the individual and for society.
