Frequently Asked Questions about Ultrasound

An abdominal ultrasound is an imaging study that uses ultrasound to evaluate the internal organs of the abdomen, liver, gallbladder, spleen, pancreas, and kidneys.

It can also evaluate vascular structures of the abdomen, as well as structures of the lymphatic system.

An ultrasound is used, which is used through a transducer the emission and reception of high-frequency sound waves. This transducer moves through the skin of the patient, and above the organ that interests to study, generating images of organs and structures within the abdomen. The same ultrasound through the transducer receives these waves and creates an image of the organ under study.

Each organ or tissue returns as a sound echo the waves that by its own structure generates given the density of the tissue to which it is formed, for example, the waves that emit bone, fluids or adipose tissue will be different.

How is an abdominal ultrasound done?

It is an ultrasound done lying down, and a transparent water-based conductive gel is applied to the skin on the abdomen that serves as a means for the transmission of ultrasound.

The doctor may need to change the position while performing the study, to examine different areas of the abdomen; you may also be asked to hold your breath for short periods during the study.

This ultrasound can be requested to investigate the cause of abdominal pain, kidney infections, diagnose tumors or ascites, and evaluate the presence of lithiasis in the gallbladder or kidney, among other possible causes for the study.

What is the preparation for an abdominal ultrasound?

The person is required to fast for at least 8 hours, to facilitate the observation of all the organs to be evaluated.

Does abdominal ultrasound generate any discomfort?

It is a study done by Ultrasound Labs that generates little or no discomfort. The conductive gel can feel a bit cold and damp. It is a rapid study in general and that the patient tolerates very well.

How long is an abdominal ultrasound?

Approximately an abdominal ultrasound study lasts about 30 minutes.

Are there risks to perform the abdominal ultrasound study?

There are no risks to perform it, since it is not exposed to ionizing radiation and neither is it an invasive study.

In an abdominal ultrasound, Doppler can also be used to increase the evaluation of the organs under study, through the study of its vascularization. In the course of Doppler, you can hear sounds similar to the pulse of an artery.

After the study, the patient can resume their activities in a normal and daily manner.

One of the benefits is low whole abdomen ultrasound price, its availability, and it does not use ionizing radiation.

An image is generated in real time, being a tool that eventually serves as a guide for minimally invasive procedures such as aspiration biopsies, and fine needle aspirations for drainage of liquids in the abdomen.

It has limitations for the study of hollow organs, that is, the intestine and the stomach mainly, since the air or gas contained in these organs reflects the ultrasound beam and prevents the formation of a clear image of the organ.

Diagnosing the Health Issues in Your Child

How can parents prevent and treat these conditions to give their children a healthy and happy adult life?

Congenital heart diseases are problems in the structure and functioning of the heart due to the abnormal development of the heart before birth. It is the most common congenital anomaly, and its presentation and treatment will depend on the type of malformation that is since there are several types.

The majority of congenital heart diseases are presented as an isolated defect without association with other diseases. They can also be part of various genetic and chromosomal syndromes, such as Down syndrome. And although congenital heart disease is present at birth, it may not be visible immediately or cause problems for years.

Although for most congenital disabilities a known cause cannot be identified, it is known that the consumption of alcohol and some chemical substances during pregnancy, and certain infections such as rubella, can contribute to its development. It is also important to control the level of blood sugar especially in pregnant women with diabetes and perform periodic ultrasounds to detect any problems.

Early prevention, the key

The first preventive measure is fetal cardiac ultrasound when the child is still in the uterus. However, the condition can be detected only years later, when the child is in early childhood, so periodic checks are essential. Besides, there are two other forms of diagnosis: puncture and nuchal translucency. Any of these types of studies must be done after week 20.

With early detection and adequate treatment, the child can be provided with quality and normal life expectancy, something that for years was unthinkable due to the lack of information and technology.

In general terms, the treatments will depend on the type of heart disease that is suffered. The milder ones disappear alone over the years, other more serious require medication and in the most complex one or several surgical procedures will be required.

Diagnostic tests

If the results of level 1 ultrasound are abnormal, doctors usually use diagnostic tests to determine if the baby has congenital disabilities or other possible problems. These tests are also offered to women with high-risk pregnancies, such as women aged 35 or older, women who have had their previous pregnancy affected by birth defects, women with chronic diseases such as high blood pressure, lupus, diabetes or epilepsy, and women who use certain medications.

High-resolution ultrasound

The ultrasound creates images of the baby. This ultrasound, also called second-level ultrasound, is used to look more closely at possible birth defects or other problems that have been indicated in the results of previous screening tests. It is usually done between weeks 18 and 22 of pregnancy.

Chorionic villus sampling (CVS)

In the chorionic villus test (CVS), the doctors of Ultrasound Clinic removes a small sample of the placental tissue, called chorionic villus, to analyze and determine if the baby has chromosomal or genetic alterations. In general, CVS is offered to women who have received an abnormal result on a first-trimester screening test or who may be at higher risk. This test is done between weeks 10 and 12 of pregnancy, before amniocentesis.

Amniocentesis

Amniocentesis is an examination in which the doctor removes a small amount of amniotic fluid from the area surrounding the baby. The fluid is tested to understand the baby's protein levels, which can indicate certain birth defects. Amniotic fluid cells can be analyzed for chromosomal abnormalities, such as Down syndrome, and genetic problems, such as cystic fibrosis.

Computed Tomography for Dental Implantation

Installing an implant requires thorough preparation. The operation is preceded by the collection and analysis of data on the state of health of the patient, the anatomical features of his oral cavity. The doctor assesses the results of the best CT scan in Delhi, a detailed image of the bones and soft tissues of the maxillofacial region obtained by computed tomography. Based on complex data, it is possible to make a prediction of implant implantation.

The method of computed tomography of the jaw is actively used in implantology. It is necessary if the panoramic picture does not give a complete picture of the features of the bones and tissues that the implantologist will deal with. The X-ray emitter rotates along the path of the helix; it can scan bone tissue, temporomandibular joint, dental roots - depending on the nature of the doctor's prescription.

A cone beam Tomograph creates a digital model of the patient’s maxillary system in 3-D format. Thus, the features of the teeth, the thickness, density and structure of the jaw bone tissue, the position of the maxillary sinuses are determined with precision. The specialist models the implantable implant calculates its inclination and the position of the jaw. The whole procedure of integrating the artificial root depends on the quality of the examination.

Also, with the help of CT, the state of filling materials in the teeth, roots, dentin, pulp, and nerve tissue is assessed. During the examination, it is possible to identify the formations at an early stage and begin their treatment.

Key advantages of using CT scanner in dentistry:

A copy of the picture is saved to external media or printed. The patient will also be able to see how his teeth will look after correcting the problem.

The method of 3D tomography is used in medical dentistry. Using a snapshot, the specialist determines the treatment method and the Osseo integration scheme. A special program allows you to test the result of implantation and eliminate complications.

How is CT performed?

A computer and a scanning device are integral parts of a dental 3D tomography. The scanner is provided with X-rays. There are two types of equipment:

The scanner is in the shape of a cylinder, in which the patient lies.

A special unit for dental offices. It has a rotating part and support for the patient's head.

Both types of scanners at CT scan Centersare programmed to take up to six images per second. All data is transferred to the computer for processing. Special software reproduces on the screen a model of the scanned area. The 3D image consists of several layers. Pictures are displayed on the monitor screen. The specialist analyzes the three layers of the scanned area: frontal, diametrical, vertical.

For security reasons and to obtain a high-quality snapshot, the client needs to perform a number of actions:

  • Get rid of metal objects (remove earrings, chains, etc., jewelry);
  • Wear a radiation protective apron;
  • Sit down or lie down, fixing the head on the support;
  • Do not move while scanning the jaw, forming a 3D image.
  • If there is a need to introduce a contrast agent, the patient should not eat and drink 4 hours before the session.
