CT scan of the coccyx
CT scan of the coccyx is one of the most informative methods in detecting bone pathology of this region. The ability to study thin slices, and availability of special modern imaging programs allow to obtain high-quality tomograms of the scanned area.
The advantages of CT compared to conventional radiography
It should be noted that in comparison with conventional x-ray radiation load on the patient during CT less, and diagnostic capabilities ten times higher. A CT scan has the possibility of constructing three-dimensional reconstruction of the scanned area that is of great importance, primarily in volumetric units. As it allows to determine the border of tumor spread, involvement of surrounding tissues in the pathological process, which is very important to assess the stage of the disease and decide on further treatment tactics.
There is also a tomographic study of the coccygeal zone allows high accuracy to visualize the bone structure, both in normal and in pathological conditions, to identify the destructive neoplastic and inflammatory processes and traumatic changes.
If you compare CT and MRI of the coccyx, magnetic resonance imaging is indicated for suspected magadane pathological conditions of this region, as well as in cases of impossibility to conduct computer research.
In what situations is shown performing a CT scan of the coccyx:
- suspected degenerative lesions of this region;
- trauma to coccyx;
- suspected destructive changes of the coccyx revealed by other methods of radial research;
- to identify anomalies;
- search of metastases in the bones of the pelvis (including the coccyx, for example, in men with prostate cancer; women – breast cancer);
- diagnostics of pain in the Sacro-coccygeal region;
- suspected lesion of the coccyx;
- differential diagnosis of benign and malignant tumors.
Contraindications to the computer study of the coccyx:
- pregnancy (and the study is contraindicated in any period; you can take only in emergencies – for health reasons, if other methods of radiological imaging does not provide adequate information for diagnosis);
- the age of 14 (it should be mentioned that computed tomography to study the coccyx can be performed in children on strict conditions, if the other radiation research was insufficient to diagnose pathological changes in this area);
- the body weight of the patient more than the allowable values for this table tomography (CT scanners have different weight limits subjects).
The study of the coccyx with the help of CT is not recommended when the patient has involuntary movements (hyperkinesias), and expressed pain. This is due to the fact that the patient cannot lie still, and artifacts from movements significantly reduce the quality of computer-generated images.
Recommended! When expressed pain syndrome before the study is recommended anesthesia.
A CT scan with contrast faux
In difficult diagnostic cases, a contrast study. Apply the preparations containing iodine (omnipak, iopamiro). Artificial contrast enhancement improves the diagnostic possibilities of the method. It shows in the first place, the differentiation of the nature of the tumor (benign or malignant), as well as in cancer to estimate the prevalence of pathological process.
Caution! CT with contrast is contraindicated in persons with a known Allergy to iodine, renal insufficiency, severe diseases of internal organs in the stage of decompensation.
Given the fact that the contrast agent enters the breast milk, nursing women should exclude breastfeeding for 2 days after the manipulation.
Preparation for the procedure
Importantly, this study does not require any complex preparation of the patient. However, two or three days before imaging is undesirable consumption of food containing fiber. Before the examination it is necessary to remove clothing containing any metal parts, to remove all the excess from the pockets (especially metal objects).
Don’t forget to bring a referral for a CT scan, discharge from outpatient cards, case histories, pictures and findings of previous radiological studies, and any other medical records relevant to the pathology of the coccyx.
Summing up, it may be noted that computed tomography of the coccyx has both pluses and minuses. The positive aspect of the research is high precision imaging of bone structures, the negative aspects may include the presence of radiation exposure, which limits its use in children and almost makes it impossible during pregnancy.
