Cross Sectional Imaging Modalities (CT & MRI) Distribution in Sohag Governorate in Correlation to Population Distribution

Background: Cross-sectional modalities (computed tomography “CT” and magnetic resonance imaging “MRI”) are the highest level of common radiological modalities that are widely used in daily diagnostic medical imaging work all over the world. The distribution of these machines in each country varies according to many factors. Sohag Governorate has one of the highest population numbers in Upper Egypt, extending along 135 km on the River Nile and located at the center between Cairo and Aswan. 
Material & Methods: This study aimed to explain the distribution of cross-sectional imaging (CT & MRI) machines in Sohag Governorate, Upper Egypt, in correlation to population distribution in the different cities. The study aimed to be a guide or plan for better radiological services, providing or supporting data for emergency planning against catastrophes. 
Results: Sohag Governorate has a total of 67 cross-sectional imaging machines (75% CT and 25% MRI) distributed over 12 cities, with about 60% of them in Sohag City. 2 cities at the same distance (33 km) on both sides of the capital city have the highest numbers of machines.
Conclusion: Imaging modalities are the main key to the diagnosis of a wide range of emergencies and diseases. Cross-sectional imaging modalities are the top of diagnostic imaging modalities. Distribution of these machines in Sohag Governorate is not proportional to the population distribution but correlated to financial factors and distribution of qualified radiologists.
