Best imaging tools for appendicitis have changed over the years. In addition, different clinicians and radiologists follow their community‘s best methods with regard to workups. In the early ‘80’s physical exams and CT In the late ‘80’s and early ‘90’s new methods using Ultrasound improved that tool but CT was still the gold standard. In the 2000s and with the desire to decrease radiation exposure, ultrasound (when there is good local ultrasound experts) became a key tool used best with thinner patients and children. Groups such as Image Gently and Image Wisely would prefer an Ultrasound t (US) To be he first exam performed for appendicitis or its simulators. If abnormal the patient would be treated. If definitively normal the concern for appendicitis would be removed. If still confusing or in a heavy patient where the ultrasound analysis is more limited CT would be the best exam. Some individuals use MR which also has l no radiation exposure but is a long and costlier exam with lesser universal national expertise. I look with US .first.I would follow with CT with continued
concern..a confusing image without a definite diagnosis. Others look at CT first

What does radiation do to a pregnant woman?

Radiation is of concern for the young fetus more so than for the parent. Radiation exposure occurs in life from our environment, air travel etc.Diagnostic radiology exposure depends on the exam performed and the area examined. A chest X ray of a pregnant patient is not preferred if unnecessary but if necessary and properly collimated will have essentially no exposure to the fetus. A pelvic X-ray on the other hand would have some exposure. Exposures in the third trimester are far less concerning after near completed fetal development than an exposure in the first trimester. Facts are: time of exposure, areas exposed, and amount of radiation used are needed to fully evaluate a given incident or theoretical one. Talk to the physician ordering such an exam to help explain the thoughts they have in the necessary balancing of needed diagnosis to protect the mother vs the need to protect the fetus.

Is varicocele embolization better than surgery?

Is one CT scan harmful?

There is radiation exposure when one has a CT. There is radiation exposure when one takes a plane ride. There are other environmental exposures we pay no attention to. Radiologists READ MORE
There is radiation exposure when one has a CT. There is radiation exposure when one takes a plane ride. There are other environmental exposures we pay no attention to. Radiologists and physicists and engineers have worked to make sure the radiation exposures in CT,
fluoroscopy etc are as ALARA (as low as reasonably achievable) so that proper imaging to make a diagnosis is performed and radiation exposure is as little as possible. Great new computers have also helped this goal.
As long as the reason for your exam is clinically appropriate, a single CT exam that gives your doctor and you an answer is a good thing. Ask your doctor to help explain what they desire to find out.

Images as seen on this software are not good enough for analysis. I am sure the original reader read them using software and a PACS system that showed them their best visual advantage. In addition, even if seen properly, the question should be discussed with you and the reading radiologist or you and the clinician who ordered the exam. If of continued concern, you should seek out (via your clinician) an official second reading (if allowed by your medical insurance).

The report is confusing. Talk to your physician regarding what he/she thinks. The report says your epididymis is infected and that infection may have entered a testicle (epididymoorchitis infection of epididymis and testicle)on the right side. The epididymis on the left is infected as well. Your scrotum is probably enlarged due to fluid surrounding it which may be due to the infection. What the infection is and how it will be treated (e.g. antibiotics) is a decision your urologist will make. I do not understand the last sentence regarding the center of the testis, the mediastinum, and its association with metastasis. Make sure the report does not have a typo by talking to your urologist.

A review of your images should be made ideally with the radiologist who performed and read out the exam. Your primary health care provider can manage the multiple types of images performed and perhaps the several radiologist readers to give you a feel for what is being said of your situation, perhaps review films with you and what the plan is for your care/rehabilitation based on those findings.
