CANCER-DIAGNOSTIC TECHNIQUES-LESSON 115

-


X-rays are used in a variety of ways to detect pathological conditions. In dentistry x-rays are commonly used to diagnose to locate cavities in teeth. Further specialities use x-rays commonly are gastroenterology, neurology, gynecology, and endocrinology, and osteology.

Contrast Studies: In x-ray film, the likely variations in the thickness of body tissues create different outline images on the x-ray film. On the other hand when x-rays get ahead of two nearby divisions made up of materials of the identical density. Such as the digestive organs in the abdomen, their images cannot be notable on the film on the screen. It is obligatory followed by to infuse a dissimilar medium called contrast medium into the structure or solution to envisage as a negative mark on the thick contrast medium.

CT or Computerized Tomography scan or CAT or Computer-Aided Tomography Scan: This is one of the avant-garde techniques in radiologic analysis. The CT scans are very much receptive to find out bone diseases in delicate bone structures and is capable of making available of pictures of internal organs that are unfeasible with run of the mill x-ray method.

In the CT scan shaft of light ionizing x-rays all the way through a patient at manifold positions as they navigate the body is sensitized and communicated to body tissues. The computer then produces all the information it takes delivery of from numerous variable x-ray outlooks and gives a multipart picture of a definite portion of the head, chest, chest, or abdomen on a screen. The facility of CT scan is to distinguish abnormalities is increased by employing of contrast agents to draw round blood vessels.


CT scans further more engage in the use of contrast dyes to find out masses in the chest, liver, kidneys, and pancreas, hematomas, brain tumors, and spinal cord lesions.
In the next lesson we will learn about attributes of x-rays. Okay.

1. Magnetic resonance imaging- A magnetic ground radio signals are used to outline sagittal, coronal, and axial pictures of the body. 2. Megavoltage- High-energy radiation engendered by means of an equipment and employed in restorative x-ray analysis intended for cancer. 3. Nuclear medicine- This is a medical speciality, which examines and employs of radioactive materials called radionuclides within identification and treatment of ailment. 4. Orthovoltage- Emission of low-energy radioactive waves that are employed in pain-killing radiation therapy and exterior skin cancer diseases. 5. Palliative- Means just soothing or painkilling, not curing completely that is not possible. 6. PET scan or positron emission tomography- Radioactive materials are administered using intravenous route and these substances give out positrons. They generate a cross-sectional picture of the metabolism of the body. These images symbolize local concentration of the radio

HUMAN BONE STRUCTURE - LESSON 200

-
Now in this post we will learn about the structure of the bone. In our human body there are 206 bones of different types are there. The thigh, lower leg, and upper and lower arm consists of long bones. These bones have large surface areas for muscle attachment and are very strong, are broad at the ends where they join with other bones. There are five types of bones in the human body. The five types are long, short, flat, irregular, and sesamoid. 1. Long bones:- These bones are comprised mostly of compact bone and lower amounts marrow, which is located within the medullary cavity, and spongy bone and are characterized by a shaft, the diaphysis, that is much larger in length than breadth. These bones are mostly present in the limbs, including those of the fingers and toes are long bones. Except the wrist, ankle, and kneecap these long bones are located in most. 2. Short bones:- These short bones are generally cube shaped and having a thin layer of compact bone surrounding a

Today, we will know about an interesting medical term in medical language. This post is just to know about a different thing in the medical language, though this word is used very rarely in our day-to-day medical transcription work. The longest medical word is "Pneumonoultramicroscopicsilicovolcanoconiosis"!!!!!. Can you read at least Pneumonoultramicroscopicsilicovolcanoconiosis.  Now, we will see the meaning of this word.  To know the meaning shall we split the word by word. Okay.  1.  Pneumono 2.  Ultramicrosopic 3.  Silico 4.  Volcano 5.  Conosis. So, Pneumonoultramicroscopicsilicovolcanoconiosis comprises of 5 medical words and in combination, they give a meaning of a certain kind of disease condition related to lungs.  Now, we will see the meaning of each to get the combined understanding of the longest medical word. Pneumono means lungs, ultramicroscopic - means minute, silico means silicon, volcano means eruption, and conosis means abnorm
