Heart computer tomography - Hospital Medical Information

이미지
Justice With the recent rapid development of computed tomography ( CT ), it has become possible to image a continuously moving heart within a short period of time. A 64-ray multidetector computed tomography (CT), widely used for cardiac imaging, has a high negative predictive value and is almost 100% less likely to be true stenosis if no stenosis is detected on CT. Dual source CT ( dual source CT ) has two x-ray tubes, doubling the acquisition time to improve diagnostic accuracy and image quality. Therefore, the burden of invasive conventional angiography has been alleviated in order to rule out the possibility of stenosis . Heart Computed Tomography ( Cardiac CT ) coronary artery stenosis evaluation, coronary artery bypass surgery graft vascular assessment, and coronary stenting and it is widely used in restenosis evaluation after its addition to the normal variability of the coronary arteries, and congenital malformations, cardiac contraction performance evaluation, the aorta ...

Computed tomography - Hospital Medical Information

이미지
Justice Computed tomography ( CT ) is performed by taking a large circular machine with an X-ray generator and taking a cross-sectional image of the human body, as opposed to a simple X-ray . CT has the advantage that structures and lesions can be seen more clearly because the structures do not overlap with each other compared to simple X-ray. It is the primary test when most of the organs and diseases are suspected and need to be performed. In terms of obtaining a cross-sectional image, the MRI and the CT are in common, but the CT acquires the image using the X-ray, and the MRI acquires the image by transferring the high frequency in the magnetic field. In addition, CT has the advantages of lower examination cost and shorter examination time than MRI . On the other hand, MRI has a higher expression and contrast of soft tissue than CT , and is the basis for diagnosis of muscle , ligament , and parenchymal lesion. Previously, MRIThe cross-sectional surface, as well as that the ...

Cerebral angiographic examination - Hospital Medical Information

이미지
Justice Cerebral angiography examination is cerebral vascular injection of contrast medium into and taken X-ray is a test to determine whether or not blood brain damage to the. A catheter is inserted into the femoral artery of the lower extremity or the radial artery of the upper limb and placed in the cerebral blood vessels. The cerebral blood vessels are seen clearly when X-rays are continuously taken for a few seconds while injecting the appropriate amount of contrast agent. In addition, in order to make only the cerebral blood vessels selectively visible, the computer can remove the peripheral shadows other than the cerebral vessels to produce a very vivid cerebral blood vessel image. Cerebral angiography tests are blood-brain tests (using magnetic resonance MR angiography ) or computed tomography (CT) brain angiography examination ( CT angiography and invasive putting foreign objects such as) and conduit, wire in the vascular contrast, may be consequent complications However,...

Cerebral aneurysm - Hospital Medical Information

이미지
Justice It refers to the case where the inner elastic layer and the middle membrane forming the inner part of the cerebral blood vessel are damaged and deficient and the blood vessel walls swell up to form a new intravascular space. More than 90% are found in the thick cerebral artery of the brain at the base of the brain called Willis ( circle of Willis ) and the rest are distal (the proximal part of the blood vessel near the heart , the distal part farther away, Which supplies blood directly to the brain ) occurs in the cerebral arteries, or in the arteries that are responsible for the larynx or horseshoe of the brain . Most cases are less than 10 mm in size but occasionally larger aneurysms may develop. More than 25 mm is referred to as a giant aneurysm. The aneurysm is divided into a cystic aneurysm, a pseudoaneurysm, and a dissecting aneurysm. Types of aneurysms Types of aneurysms cause The exact cause of the aneurysm is unknown yet. However , it is presumed that an...

Why do you feel dizzy when you are exercising and suddenly dizzy?

Related diseases          Vagus nervous fainting Department of Medicine  Cardiology Q. When I was exercising, I felt dizzy and suddenly the sky was dizzy with dizziness. Why? A. vagus vascular neurogenic syncope ( vasovagal syncope ) is first suspected. Vascular vagus nerve palsy has no abnormality in the heart itself, but some external factors temporarily cause an imbalance in the autonomic nervous system, which slows the heart rate and lowers the blood pressure, leading to loss of consciousness and collapse. It occurs mainly in the younger layer, and is caused by a variety of external stimuli such as closed air with cloudy air, frequent sitting or standing in a hot place for a long time, disgusting smell, horrible sight, severe pain, defecation, urination, Vagus nervous system is activated, and syncope occurs. Confirmation is a test of incontinence called slope table test. Of course, the possibility of arrhythmia is not completely ex...

After a gout attack, the lid continues to grow. Should I look at this as gout?

이미지
Gout occurs when suddenly the toe, the wind only hurts (even graze 痛風 will feel severe pain enough to be very high expression). This is because leukocytes in the body are severely inflamed during the process of eliminating the uric acid crystals formed in the joints or around the joints. At this time, anti-inflammatory treatment should be started with ice fomentation. The most commonly used is oral anti-inflammatory (anti-inflammatory) agent. If these anti-inflammatory treatments are done early, most focal gout attacks are effectively treated. Gout attacks usually do not require anti-inflammatory treatment, but the inflammation gradually improves over time. However, without proper antiinflammatory treatment, arthralgia can last for weeks, so it is advisable to start anti-inflammatory treatment as soon as you have gout attacks. If the joint is still uncomfortable even though you think it has passed, you may still have symptoms because the severe inflammation has not co...

I'm trying to fix the damn ventilation. Please tell me what to eat and what to avoid.

Gout is associated with the accumulation of uric acid in the body. Uric acid is the final product of degradation caused by metabolism of a substance called purine, a component of nucleic acid, in the liver after the cell has reached its end of life and the nucleic acid has been liberated. Purine, a precursor to uric acid, is ingested through food. When purines are metabolized in the liver and become uric acid, uric acid is excreted in the urine via the kidneys. If you have gout, you should know and eat foods that have high purine content (liver, kidney beans, herring, mackerel, anchovy, etc.). Alcohol as well as diet are closely related to the occurrence of gout. Alcohol reduces the excretion of uric acid in the body, and drink with alcohol is said to increase the amount of uric acid in the blood because of the high purine content. Among beer, beer is known to cause gout attacks most commonly because of the presence of purine in beer. Regardless of the type and amount of alc...
