Summary
Kazakhstan
Area of Science:
- Medical Imaging and Radiology
- Occupational Health and Safety
- Public Health Policy
Background:
- Diagnostic radiology is crucial in healthcare, but access and occupational radiation exposure are understudied in Kazakhstan.
- Rapid growth in radiology services presents challenges in workforce distribution and radiation safety.
- Concerns exist regarding radiation exposure and anxiety among medical personnel.
Purpose of the Study:
- To evaluate national trends in diagnostic imaging services and workforce in Kazakhstan (2018-2024).
- To assess individual radiation exposure and radiation-related anxiety among medical personnel.
- To identify factors associated with occupational anxiety in radiology professionals.
Main Methods:
- Analysis of national diagnostic imaging infrastructure and workforce data (2018-2024).
- Review of individual radiation exposure data (n=177) from dosimetry records.
- Cross-sectional survey (n=324) using the Spielberger-Hanin Anxiety Scale.
Main Results:
- CT rooms more than doubled (+121%), while X-ray and fluorography examinations declined significantly.
- CT scans increased over threefold; radiologist and ultrasound doctor numbers grew substantially.
- Interventional physicians had the highest radiation doses; 32% of radiology professionals reported anxiety, linked to inadequate safety practices.
Conclusions:
- Kazakhstan's diagnostic radiology capacity has expanded rapidly, particularly CT availability.
- Regional disparities and occupational anxiety among radiology professionals are significant concerns.
- Improved workforce distribution, protective measures, and safety training are essential.

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
377
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

01:20Imaging Studies for Cardiovascular System III: X-Ray
451
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
