Double Contrast | Examination of the small intestine according to Sellink

Double Contrast Double contrast is the term used to describe the phenomenon used for diagnostics in the small bowel examination method according to Sellink. The patient initially receives a positive contrast medium that is not absorbed by the intestine and therefore remains in the lumen. The intestine is then filled with a negative contrast medium, … Double Contrast | Examination of the small intestine according to Sellink

Bone Density Measurement

Synonyms Osteodensitometry engl. : Dual Photon X-Ray = DPX Definition In a bone densitometry procedure, a doctor uses a medical-technical procedure to determine the bone density, i.e. ultimately the calcium salt content of the bone and thus its quality. The result of the measurement provides information about how fracture-resistant a bone is and is used … Bone Density Measurement

Quantitative ultrasound examination | Bone Density Measurement

Quantitative ultrasound examination The third and last option for bone density measurement is quantitative ultrasound (QUS), in which ultrasound waves are sent through the body instead of X-rays. As a result, the radiation exposure in this procedure is zero. Ultrasound waves are also attenuated to varying degrees by tissue of varying density and can therefore … Quantitative ultrasound examination | Bone Density Measurement

Costs of bone densitometry | Bone Density Measurement

Costs of bone densitometry Since the year 2000, bone densitometry has only been paid for by statutory health insurance companies if at least one bone fracture attributable to osteoporosis is already present or if there is a strong suspicion of osteoporosis. Early detection of osteoporosis using bone densitometry, on the other hand, is not covered … Costs of bone densitometry | Bone Density Measurement

Risk of bone fracture | Bone Density Measurement

Risk of bone fracture Although bone densitometry is very important in the diagnosis of osteoporosis, it is not the only aspect that plays a role in the risk of fracture. Therefore, the WHO has developed a model that incorporates 11 risk factors (including age and gender) in addition to bone density into an algorithm that … Risk of bone fracture | Bone Density Measurement

Cardiac catheter examination

Coronary angiography A cardiac catheter examination is a diagnostic or therapeutic measure to detect and correct cardiovascular changes with the help of a catheter inserted into the vascular system. A cardiac catheter is a very thin, internally hollow instrument several meters long, with a guide wire in its central cavity. This guidewire serves to guide … Cardiac catheter examination

Heart catheter OP | Cardiac catheter examination

Heart catheter OP The aim of cardiac catheter surgery is to examine the coronary arteries or the heart itself more closely with the aid of a contrast medium and X-ray technology. A cardiac catheter operation is performed as follows. First, the patient is prepared for the operation in the cardiac catheter laboratory. Since the physician … Heart catheter OP | Cardiac catheter examination

Risks | Cardiac catheter examination

Risks As with any procedure, in some cases (cardiac catheterization) complications can also arise from a cardiac catheterization. Since the cardiac catheter is advanced through the arterial vascular system into the heart, it is also in close contact with the cardiac conduction system, which is responsible for each individual heartbeat. If the nervous system is … Risks | Cardiac catheter examination

Wrist access | Cardiac catheter examination

Wrist access The puncture site for the introduction of the cardiac catheter is usually made through a venous or arterial access of the groin, elbow or wrist. The access at the wrist is transcarpal, i.e. via the carpus. There are then two possible arterial accesses, namely the radial artery or the ulnar artery. The radial … Wrist access | Cardiac catheter examination

Myelography

Synonyms Contrast medium imaging of the spinal canal (syn. spinal canal). Definition A myelography is an invasive (bodily harming) diagnostic X-ray procedure for the clarification of back pain when there is a suspicion that the cause of the pain is related to a compression of the spinal cord (myelon) or spinal nerves and other modern … Myelography

Preparation | Myelography

Preparation Before a myelography, some preparation is necessary. The doctor is obliged to thoroughly inform the patient about the nature and necessity of the examination. He must also inform the patient about the general and intervention-specific risks. In turn, the patient must give his written consent to the myelography at least one day before the … Preparation | Myelography

Pain | Myelography

Pain Myelography is a low-risk routine procedure. Only the injection of the contrast medium in the lumbar region (between L3 and L4) can cause risks for the patient. A rare complication is the occurrence of pain during the examination. These occur due to injury to nerve fibers during puncture with the myelography needle. Patients often … Pain | Myelography
