When X-rays are not enough
Radiography remains the first method in case of injury, but in complex multi-fragmented and intra-articular fractures, it does not allow an accurate assessment of the number of fragments, the degree of their displacement and the involvement of the articular surface - and this is what determines the choice of osteosynthesis method. CT with three-dimensional reconstruction gives the surgeon a three-dimensional picture and allows you to plan the operation in advance. The study is also used to monitor fracture consolidation if delayed healing or formation of a false joint is suspected, in the diagnosis of bone tumors and osteomyelitis, where assessment of bone destruction is important.
What is the power of computed tomography?
MSCT creates an image using X-rays and produces thin sections with high spatial resolution. It is indispensable where bone, lung tissue, fresh hemorrhage and precise vessel geometry are important, as well as in emergency situations - the examination takes seconds.
Three-dimensional reconstructions are constructed from the resulting sections: this allows the surgeon to see the anatomy in volume in advance and plan the intervention.
When you need contrast
Intravenous contrast dramatically increases the information content in the study of blood vessels, tumors, inflammatory processes and parenchymal organs. It shows the nature of the blood supply to the formation, which often determines its nature.
Before a contrast study, kidney function is assessed by creatinine level and an allergic history is clarified - reactions to iodine-containing drugs are rare, but require attention.
CT or MRI
- CT scan is better: bones, lungs, acute hemorrhage, stones, vessels, emergency conditions
- MRI is better: brain and spinal cord, soft tissues, joints, pelvis, liver
- CT is faster and more accessible, MRI does not provide radiation exposure
About radiation exposure
Computed tomography uses x-rays and is therefore prescribed according to indications. Modern machines use dose reduction protocols, and the information obtained from sound research usually far outweighs the risk. During pregnancy, CT scans are performed only for health reasons.
