USE OF ULTRASOUND AND MRI TECHNIQUES-LESSON 134

-

Ultrasound: High-frequency impossible to hear muffled sound waves are sent and these waves are bounced off by body tissues. The movement of sound waves are recorded to give the information about the structure of the inside organs. The good transmission of waves is ensured by placing an instrument near the skin and by smother the skin surface by an oily substance. Oil substance probably a mineral oil is put for the diffusion of sound waves properly.
The ultrasound instrument produces dumpy sound waves in cyclic beats. Each wave is in different speed of motion and invades through the tissues inside the body and becomes aware of boundaries amid tissues of diverse compactness. These waves are passed back to the ultrasound monitor and recorded. This record is called echogram or sonogram.
This instrument is used not only by radiologists, but also by ophthalmologists to detect intracranial and ophthalmic lesions. Cardiologists also use this instrument to identify blood valve and heart valve ailments. This is called echocardiogram.
Gastroenterologists use this equipment to track down of any abdominal masses in the GI tract.
Gynecologists and obstetricians use this equipment to make a distinction between whether there is a single child or more than one in the uterus.
Obstetricians perform amniocentesis to track down tumors or cysts if any in the uterus. Measurement of fetal size and age of the fetus can also be calculated using ultrasound wave technique.
ADVANTEAGES OF THE ULTRASOUND:
Comparing iodine contrast study and other studies ultrasound is very safe and has side effects as the sound waves used in this method are nonionizing. Passing these waves inside the body will not damage the internal organs or any tissues.
In the next post we will study about Different views of x-ray positions. Okay.
Come on.

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
