List Diagnostics – C
Screening cytological methods. They are performed for the purpose of early detection of uterine and cervical cancer. The nature of the pathological process is recognized based on the following features: morphological features of cells, quantitative relationship of individual cell groups, location of cellular elements in the preparation.
Cystometry is a basic method of urodynamic research, during which both phases of the urination cycle are examined - filling (accumulation) and emptying, and the dependence of intravesical pressure on the degree of filling of the bladder is studied.
Cystography is a medical procedure used to examine the bladder and urinary tract using x-rays or other imaging techniques.
CT myelocisternorrhaphy is a method that combines the capabilities of CT and myelography. It is an invasive method of obtaining images, as it requires the introduction of a contrast agent into the subarachnoid space.
CT angiographic images must be analyzed in different projections MIP (maximum intensity projection), MPR (multiplanar reconstruction) or three-dimensional reconstruction VRT (volume rendering method).
When performing spontaneous breathing with continuous positive airway pressure (CPAP), pressure fluctuations inevitably occur, but it always remains higher than atmospheric pressure.
Coronary angiography continues to be the “gold standard” for diagnosing coronary artery stenosis, determining the effectiveness of drug therapy, PCI and CABG.
Keratoplasty (corneal transplant) is the main section in corneal surgery. Corneal transplant has different target settings. The main goal of the operation is optical, i.e. restoration of lost vision.
The cornea is a highly sensitive membrane of the eyeball. In various pathological conditions of the eye, its sensitivity can significantly decrease or completely disappear, so its determination can be a very informative indicator when establishing a diagnosis.
Assessment of corneal sensitivity in order to identify gross disturbances of corneal sensitivity.
Corneal scraping is performed with a Kimura spatula, a curved needle tip (for the hypodermis) or a blade. After instillation of a local anesthetic without preservatives, the edges and bottom of the lesion (usually an ulcer) are carefully and thoroughly scraped under slit lamp control.
Pachymetry is a measurement of the thickness of the cornea. It is an indirect sign of the integrity of the corneal endothelium. The greatest thickness of the cornea is at the limbus (0.7-0.9 mm).
Corneal keratometry is the measurement of the curvature of the axial meridians of the anterior surface of the cornea.
Systematic identification of clinical signs, determination of the location, depth and size of corneal damage is of great importance.
Contrast ventriculography (VG) is one of the important catheterization angiographic methods. Ventriculography is the contrasting of the ventricle of the heart with recording of the image on film or another recording device (video film, computer hard or CD-disk).
Dacryocystography is also useful in diagnosing diverticula, fistulas, and filling defects caused by stones or tumors.
Contact vision correction has a centuries-old history. Leonardo da Vinci and Rene Descartes were interested in this issue.
The conjunctiva is easily accessible for examination and diagnosis of many of its diseases and does not require any special equipment.
Cricothyrotomy (cricothyroidotomy) involves opening the cricothyroid membrane when tracheal intubation is impossible or there is obstruction in the larynx. The main advantages of this method are the simplicity of technical execution and the speed of execution (compared to tracheostomy).
Confocal microscopy of the cornea is one of the modern research methods; it allows for intravital monitoring of the cornea with tissue visualization at the cellular and microstructural level.
