Hi !
Which of these is an advantage of a CT scan over an MRI?
D. It can guide treatment of cardiac disease
An advantage of a CT (computed tomography) scan over an MRI (magnetic resonance imaging) is that CT scans typically use less radiation. CT scans utilize X-rays to create detailed cross-sectional images of the body, while MRI scans use magnetic fields and radio waves to generate images.
The correct option is B.
Since CT scans involve the use of X-rays, they do expose the patient to ionizing radiation, although the amount is generally considered safe for diagnostic purposes. However, compared to a CT scan, an MRI does not involve exposure to ionizing radiation at all.
It's worth noting that the choice between a CT scan and an MRI depends on various factors, including the specific medical condition being investigated, the required level of detail, and any specific concerns about radiation exposure. In some cases, an MRI may be more suitable despite its lack of ionizing radiation, such as when examining soft tissues or organs where MRI provides better visualization.
Hence , B is the correct option

The _forms food into balls
ANSWER:
The salivary amylase makes food into balls. The process of digestion starts in the mouth when the food eaten is chewed.
EXPLANATION:
In the mouth, the "salivary glands" secrete an enzyme called amylase that breaks down the food or long starch molecules into maltose. When the food is ready to be swallowed, it is "gathered into a ball" called bolus. The bolus is then sent to the pharynx from where the food goes to the oesophagus and eventually to the stomach.Little hairs that line the nasal cavity that trap microorganisms as the air passes through are known as

The little hairs that line the nasal cavity and trap microorganisms as the air passes through are known as cilia. These microscopic, hair-like extensions are located on specialized cells in the lining of the nose and all breathing tubes and serve to trap and remove dust, germs, and other foreign particles. Cilia are part of the respiratory epithelium, which produces mucus to increase the trapping efficiency. Furthermore, the cilia beat in a wave-like motion to transport the trapped debris towards the throat where it can be swallowed and safely eliminated from the body.

Provide an example of changes over the years that may have prompted the public to opt for this procedure to correct their vision
The Laser-Assisted in Situ Keratomileusis (LAISK) is one of the changes over the years that have prompted the public to use and correct their vision.
With rapid advancement in technology alot of procedures which includes LAISK is carried out by specialists on patients with eye defect to correct their vision.
The cornea is a clear protective covering at the outer layer of the eye.
If the cornea becomes damaged through disease, infection or injury, the resulting scars or discoloration can interfere with vision by blocking or distorting light as it enters the eye.
The Laser-Assisted in Situ Keratomileusis can be used to correct eye defect that occurs due to damage to cornea.
In LASIK surgery, a special type of cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eye (cornea) to improve vision.
This method has prompted the public to opt for it because it's a better alternative to the use of glasses or contact lenses.

Significant advances in laser vision correction, such as improved safety, effectiveness, and the development of innovative procedures for conditions like AMD, have motivated the public to choose surgical options like LASIK over traditional lenses for vision correction.
Explanation:Over the years, there have been significant advances in laser vision correction procedures such as LASIK (Laser-Assisted in situ Keratomileusis). These advancements have significantly improved the safety and effectiveness of the procedure, leading to greater public trust and an increased tendency to opt for surgery over traditional lenses. Initially, vision correction was primarily achieved using eyeglasses or contact lenses to manage conditions like myopia (nearsightedness) and hyperopia (farsightedness). However, these methods can be inconvenient and hinder certain activities.
The development of procedures like LASIK allows for a more permanent correction by reshaping the cornea using high-intensity electromagnetic radiation to adjust its curvature. This change corrects the refractive error by focusing light properly onto the retina. For myopia, the cornea is flattened to reduce its power, whereas for hyperopia, the cornea's curvature is increased, enhancing its power. Furthermore, the advent of sophisticated technologies and techniques has made laser vision correction safer and more precise, providing an incentive for individuals to choose this form of treatment. An example of innovative surgical advances is stem cell operations, such as the one performed by Dr. Pete Coffey, which aim to treat conditions like age-related macular degeneration (AMD) and have the potential to become as regular as cataract surgery. These medical advances promise not only to correct vision but also to address and potentially reverse underlying degenerative conditions.

You have damaged the tendons or ligaments of your wrist. The repair will require surgery. In order to learn the extent of the injury and then monitor the healing process after the surgery, images of the damaged wrist are needed. WHICH METHOD (mri, ct scan, or x-rays) IS THE BEST TO USE FOR THIS TYPE OF INJURY? INCLUDE A DISCUSSION OF THE PROS AND CONS OF EACH TECHNOLOGY TO SUPPORT YOUR DECISION.
Answer: CT is the correct anser.
Explanation: All of the other types of scans do not look very far into your body and mostly just look at your bones. A CT scan is extremely more precise and can look for your damaged tendons and ligaments.
Answer:
The answer is: Magnetic Resonance (MRI).
Explanation:
Magnetic resonance imaging (MRI) uses a powerful magnetic field, radio waves and a computer to produce detailed images of joints, soft tissues, and bones. It is generally the best way to evaluate the body for lesions, tumors, and degenerative disorders.
The term "computed tomography," or CT, refers to a computerized procedure of x-ray images. These tomographic images contain more detailed information than conventional x-rays.
But as with all X-rays, it is easy to obtain images of dense structures, such as a bone inside the body, while soft tissues vary in their ability to stop X-rays and, therefore, are weak or difficult to visualize.
The answer is: Magnetic Resonance (MRI).

A)disease reporting
B)drug prescriptions
C)self-exams for breast and testicular cancer
D)disease diagnosis
The responsibility of public health includes A) disease reporting, which fits the activities aimed to prevent and control diseases by tracking disease incidence and prevalence.
The responsibility of public health generally encompasses a wide range of activities aimed at preventing and controlling diseases. A) Disease reporting fits under the umbrella of public health since it involves tracking the incidence and prevalence of diseases within a population to prevent and control outbreaks. Public health authorities often require physicians and other healthcare providers to report certain notifiable diseases, such as HIV, tetanus, cholera, and malaria, among others. This reporting is crucial for maintaining public health surveillance systems that monitor the health of a community and can trigger a public health response when needed.
For instance, cancer reporting requirements are typically more extensive compared to other conditions. Healthcare providers must report detailed information about cancer diagnoses to health departments, which can be used for surveillance and research, as seen in the Surveillance, Epidemiology, and End Results (SEER) database. Public health officials may also be involved in screening programs, which involve testing asymptomatic individuals for conditions such as cancer to enable early treatment. These screenings can include mammograms for breast cancer detection or skin checks for melanoma risk.
