Radiolucent indicates a structure which lets relatively more x-rays through than the adjoining structures. The radiolucent structure is black on film, and the radio-opaque structure is white. Everything is relative. From radiolucent to radio-opaque, in a progressive order are air, fat, water (soft tissues), bone, metal.

Black coffee is fine, see below. On the Day of the CT Scan * Do not eat any solid food for 4 hours prior to your CT scan. You may drink clear liquids up until the time of your scan. Clear liquids include water, black coffee or tea, apple juice, clear soda or clear broth. UCSD Medical Center

As we know,Clarity of the image is decided by its Spatial Resolution but not by Pixel Resolution.

CT have high Spatial Resolution but MRI have comparable Spatial Resolution to CT&far better Contrast Resolution than CT-So,MRI is the BEST to demonstrate Anatomy,especially in parts containing more soft tissue[Eg:Brain]&CT is the BEST to demonstrate Bony Anatomy.

my husband has just had an apendicitis. In the CT scan it was found (incidental finding) two hypodense focal massess in the neck of the pancreas that will require follow up (MRI). We are freaking out. What could that mean? is it smething seriois or somethig normal? Thanks

MRI is Magnetic Resonance Imaging and a CAT is a computerized X Ray (Computer Assisted Tomography)

MRI will work fine in case of diagnosis of soft tissues and CT will work fine for bony structures and inner ear analysis.

Also MRI do not use any radiation it is based on magnetic effect so less side effects compared to CT which uses X- rays.

MRI is very much costlier compared to CT.

MRI is problematic in case if the patient is having some metallic implant, which will cause interference with the magnetic field.

In order to determine any hairline crack then MRI would be preferred compared to CT.

An imaging scan that measures the activity or functional level of the brain by measuring its use of glucose.

Positron emission tomography, a process that uses radiation to give you a 3d image of the body.

PET scans are used to view nodules in the lungs or pleural cavity and check other organs for infiltrates or spots, such as a spot on a kidney which can't be seen on regular x-ray equipment. It defines and makes problems clearer to see.

They are the same thing. CAT stands for Computerized Axial Tomography which was later changer to just CT or rather Computerized Tomography. The scanners originaly only did axial images (referring to the plane of the image) but later became able to do other planes such as coronal or saggital imaging and can now do anything with the block of information it collects.

hypodensity often means that there is edema, or swelling in that area of the brain. Therefore, this could indicate that there was an ischemic stroke that occurred within the parietal area of the brain. Hope this helps.

A bone scan, or x-ray is simply a different type of scan than an MRI. No kind of scan is better than another, it simply depends what the scan is trying to ascertain.

C-T, or computed tomography, is a series of x-rays done in 3 dimensional 'slices' of the study area of the body, which allows for very specific detail of the imaged area. A C-T may be either non-contrast, contrast, or both. No matter what part of the body is being imaged, the liquid contrast material is injected intravenously. A nurse or specially trained technician will start an IV, usually in the arm, and inject the contrast material, and then the C-T scan is performed. If both non-contrast and contrast studies are being performed, the non-contrast study is done first.

No, you can't. The high energy photons pass through you, and will do some damage to the tissues of your body because they are ionizing radiation, but you will not be able to feel it.

A PET scan is a scan of the brain to see what's going on inside. It is used for cancer patients to find out exactly where the tumor is and make surgery easier.

CT Scans are of importance because they provide us with a better picture of thicker tissue inside the human body. With them we're able to look at organs such as the brain, which is CT scanned very often. I myself have had seven CT scans of my brain taken and they showed my doctors that I had cerebral edema, swelling in my brain. They can also show hemhorages and other cranial injuries.
