My Answers

Does this CT indicate pulmonary hypertension or fibrosis?
The report does not sound concerning for either pulmonary hypertension or asbestosis in particular. Go over the report with your clinician or radiologist, if you can. Reports may not indicate image findings exactly the same among various readers. While ascending aorta diameter is typically less than 2.1cm, upper limits of normal have been considered as high as 3.56 cm in the 20-40 age range. Again, however, you need to get the info about your images and your reading from your ordering doctor or imaging radiologist who has seen the images. READ MORE
Does a neck CT scan show your thyroid?
A neck CT includes the thyroid if it is in its normal position in the neck. READ MORE
Tablets given before cat scan?
Pre CT and posts pills are not anything that is given to patients. Seek out information from the team that imaged you as to what pills you were given both before and after a CT. READ MORE
Ct scan results?
Reword the question. CT colonography is a specialized form of CT (air distending a cleaned-out colon) that can help pick up colon malignancy by showing a gastroenterologist where a possible mass is for biopsy and a polyp for possible removal. Routine CT of the abdomen would typically not pick up a polyp within the colon. Decisions as to how often to undergo colonoscopy or CT colonography depend on age, family history, and medical organization recommendations. Talk to the gastroenterologist who ordered your original T if it was a CT colonography. READ MORE
What happens after CT scan with contrast?
In the usual case..the contrast is well tolerated. It is voided out of the body. The images are read by a radiologist. The information given to the clinician helps in making medical decisions. READ MORE
Is an MRI or CT scan better for sinuses?
It matters what the exam is searching for. Currently, CT is a more traditional method for sinus evaluation allowing the best evaluation of bones as well as excellent evaluation of mucosa. MR is more limited for bone analysis. CT had radiation exposure. MR does not. READ MORE
Why would a doctor order a CT scan for pneumonia?
There are multiple potential reasons. The first thing would do is ask the ordering doctor. The information should be made clear. There may be clinical reasons e.g.: Pneumonia that does not get better. There may be imaging reasons based on findings on the plain film e.g. a circular area that may be pneumonia or a mass simulating one or overlying densities that confuse the reader. There may be historical reasons added to the plain x ray finding eg work-related inhalation findings, smoking history, etc. CT of the chest is a very helpful test to answer confusing aspects of history, clinical findings, and/or x ray findings. READ MORE
How is a CT scan of your chest done?
Chest CTs are performed like any CAT scan. You are placed on your back (typically), on the machine's tabletop partly within the CT machine's body opening. The machine takes its images within seconds and its computers manipulate those pictures and move those images to a Picture Archiving System (PACS) from which the radiologist analyzes them. Technologists place you on the tabletop of the machine and help you get off of the machine. Getting onto the tabletop and set up for the exam takes longer than the actual x-ray portion of the CT exam, which is very brief. Radiographers or a Recorded Voice may tell you commands such as holding your breath or do not move as with most x-ray exams. In most instances, Chest CTs are performed without the injection of contrast material into an intravenous line in your arm. However, decisions on how a specific exam is performed are based on why you need the exam, what the ordering doctor wants to know and the methods decided on by expert groups on how a specific exam should be performed. It is a fast and painless exam. Do not worry. READ MORE
What can a CT scan detect in the lungs?
A Chest CT can evaluate many things. Certainly all the anatomy from the front to the back of the person evaluated from the top slice (often including the low neck) to the bottom slice (including the lower lung which allows imaging of some of the liver, spleen, and adrenal at that level. The lungs themselves and the nearby structures such as the heart, pleural lining, mediastinum are key t areas that can be evaluated. Different CT methods are used for more specific findings desired by the requesting physician. Talk to the ordering doctor to know what they are asking to find out. READ MORE
Can a CT scan detect a lung infection?
Lung infections have different effects on lung tissue. Other conditions can cause in some cases similar findings. A CT can help note, and strongly suggest, but not prove without microbiological confirmation, lung abscesses, pneumonia, pleural collections, and other "infections" within the thorax ( chest cavity ). One can have a bronchial infection that may not be seen. There are no simple and complete answers. Chest CT is a very helpful diagnostic tool for a variety of thoracic abnormalities. READ MORE
Why do you have to drink iodine before a CT scan?
You do not “have” to drink iodine for a CT. Iodinated contrast materials are given by mouth at some centers in liquids so that the swallowed material will be dense enough to be seen within the examined lumen of stomach, small or large bowel as white material. Depending on the goal of the CT examination, the radiologist or the radiology group may not need an iodinated contrast filled stomach and/or bowel. Some groups use water as a substance to drink to allow the stomach and duodenum to be evaluated with water appearing not dense or white, but rather gray to black easing visualization of the bowel walls.

Covid and radiology (mammogram)?
An X-ray exam is not a contraindication for a COVID test, an immunization, or that immunization’s booster. There is no connection. READ MORE
Do you ever fully recover from radiotherapy?
There are many different methods for the treatment of a variety if tumors via radiotherapy. How people feel clinically before, during after radiotherapy depends on the malignancy, its size, stage and what it has done by the time of treatment as well as the varied ways people react to any treatment. A generalized answer can not be given. Discussions re: the individual’s case with their radiotherapist who knows all the information I noted would be best for a helpful answer. READ MORE
Can you see a hiatal hernia on x-ray?
Hiatal hernia is best seen after contrast is placed in the stomach usually by swallowing and patient is evaluated sometime while bearing down. However, an air-filled wide structure above the diaphragm can occasionally be seen on plain film suggesting a hiatal hernia. Speaking to your primary care physician may aid. Harris l. Cohen, MD READ MORE
I have a bump on my head from a fall?
See a clinician to assess if what you are talking about is a hematoma from a fall (and being on Warfarin) or some other mass. The clinician will determine if the mass is merely superficial to the bone or crossing the bone from clinical exam and the CT that has already been taken. Once a clinician decides what the concern is, then the type of imaging exam needed can be determined. READ MORE
How can we avoid mobile radiation during pregnancy?
I am confused about what is "mobile radiation." There is radiation exposure that occurs in day to day living which may be affected by where you live (level above sea level), what you do as your work (eg increased exposure for airline workers while flying) and what materials your home is made of (e.g., re: radon exposure). Unless egregious, no warnings are necessary for pregnant individuals going about their day to day activities. Talking to one's obstetrician may provide resources and conversation to allay one's fears. Harris L. Cohen, MD, FACR READ MORE
How long do you have to stop metformin before a CT scan?
Metformin stoppage for CT is only with CTs that use intravenous contrast. Stoppage extends for 48 hours after the procedure and its IV contrast usage. Knowledge of the exact requested exam via the ordering clinician and the radiologist in charge of the exam is necessary. Each institution has their particular protocols. Discussions with your physician as to whether a substitute for metformin is desired during the preCT and post exam "48 hours" should be had. Harris L. Cohen, MD, FACR READ MORE
What is the success rate of radiation therapy?
Radiation therapy is different for different malignancies. Treatment techniques evolve over time. Some cancers are highly susceptible to radiation therapy. Match the therapy with the specific malignancy and you can find out the success rate. Harris L. Cohen, MD, FACR READ MORE
At what stage of cancer is radiotherapy used?
There are many types of cancers. There are many ways to treat them. Some respond well to radiotherapy. Decisions as exactly to whom or when radiotherapy should be given is part of the expertise of the radiotherapist. Harris L. Cohen, MD, FACR READ MORE
What is the prep for a CT scan?
CT scan prep is different for different institutions and different imaged areas. There is usually none other than being off food and drink for a designated number of hours prior to the exam. This can help visualization of the gallbladder and help the patient avoid aspiration should the study require intravenous contrast. In the occasional patient, they may vomit in reaction to the contrast material. CTs are usually simple and fast exams that provide radiologists with a great deal of anatomical and at times physiologic information. Harris L. Cohen, MD, FACR READ MORE
