CT scan

Understand the ct scan procedure: when it is recommended, how it is done, safety, and how results are reported.

MR angiography: vascular diagnostics without a catheter

Magnetic resonance angiography (MR angiography), unlike spiral CT, conventional angiography, and digital subtraction angiography, allows for the visualization of blood vessels even without the use of contrast. The examination can be performed in 2D or 3D.

MRI of the brain: magnetic resonance imaging

MRI assesses the condition of brain structures based on their outline, size, and tissue density. It's important to note that MRI reflects tissue density based on its water content, and therefore primarily identifies lesions such as cerebral edema (CEE), demyelinating diseases, and tumors.

CT myelocisternography: indications and technique

CT myelocystorrhaphy is a method that combines the capabilities of CT and myelography. It is an invasive imaging technique, as it requires the injection of a contrast agent into the subarachnoid space.

Tomography of the maxillofacial region: indications and possibilities

Maxillofacial tomography is used when difficulties arise in evaluating the summation image on conventional images. These difficulties may be due, in particular, to the complex anatomical structure of the maxillofacial region.

CT angiography: vessels, contrast, and risks

CT angiographic images must be analyzed in different projections MIP (maximum intensity projection), MPR (multiplanar reconstruction) or 3D reconstruction VRT (volume rendering method).

Abdominal CT Scan: What it Reveals

All parenchymal organs should be equally well visible. The only exceptions may be the presence of a partial volume effect and the early arterial phase of contrast enhancement during spiral scanning. Structures such as blood vessels and intestinal loops should also be clearly visualized against the background of fatty tissue. The same applies to muscles.

Chest computed tomography: indications and preparation

Typically, chest examinations are performed transversely (axial slices) with a slice thickness and scanning increment of 8-10 mm. For example, when performing 10 mm thick slices with a 1 mm overlap, the table advances in 8 mm increments.

Computed tomography of the neck: indications and preparation

Unless contraindicated, a CT scan of the neck is performed after intravenous administration of a contrast agent. The use of contrast agents allows for more reliable detection of malignant tumors and inflammatory processes. Adequate enhancement of the neck vessels requires a larger amount of contrast agent than, for example, a CT scan of the head.

Computed tomography of the head: main pathological findings

A direct consequence of a head injury is a brain contusion, accompanied by hemorrhage. Acute hemorrhage appears as an area of increased density with swelling of the surrounding tissue and displacement of adjacent brain structures.

Normal CT Scan of the Head: What Does Normal Look Like?

Scanning typically begins at the base of the skull and proceeds upward. The resulting images on film are oriented so that the slices are viewed from the caudal side (from below). Therefore, all anatomical structures are inverted from left to right. The topogram shows the location of each slice.
