Ovarian cyst after CT scan now going for ultrasound to see what?

Ovarian cyst after CT scan now going for ultrasound to see what?

More information: Ultrasound can better assess if the cyst is simple, has blood products in it, or is a associated with a soft tissue mass. Color doppler on ultrasound further adds information about blood flow around the cyst. You should know the great majority of ovarian cysts are benign but your doctor can better know from the ultrasound if there is anything concerning or if a followup ultrasound would be useful.

Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

Which is more useful in determining wether an ovarian cyst is cancerous CT scan or ultrasound?

Which is more useful in determining wether an ovarian cyst is cancerous CT scan or ultrasound?

CT always better: CT is always better than ultrasound but for screening purposes the ultrasound causes no radiation effect. If multiple CTs were performed over time the RT could be significant. The ultrasound can tell whether a lesion is solid or cystic and whether the latter is simple or complex. The CT can show detail not seen on ultraound.

My 15 yr old daughter's CT scan & ultrasound shows a right complex ovarian cyst, septated 6cm. 1st appt Monday seeing Gyn Dr. What is usually done?

To OR to rule out ca: Unfortunately, the only reliable way to tell if her ovarian tumor is benign or malignant is through exploratory surgery, preferably performed by an experienced gyn oncologist who will be prepared to remove the least if the intraoperative findings are benign and who can adequately "stage" her if a cancer is discovered. Seek a consultation and the care from such a gyn ontologic surgeon and team.

Had a CT scan @ ER that diagnosed a 3.6 CM ovarian cyst, followed up with gyno who did no extra tests and sent me back home, do I need a sonogram?

Had a CT scan @ ER that diagnosed a 3.6 CM ovarian cyst, followed up with gyno who did no extra tests and sent me back home, do I need a sonogram?

Painful or not?: If the cyst isn't painful, it will likely rupture or go away on its' own and a ultrasound would only be needed if there is pain involved in follow up.

Is it possible to miss an ovarian cyst on a transvaginal ultrasound and find it on a CT scan?

Possibly: No test is 100% perfect and anything can be missed on any diagnostic test especially if it is small. In general ultrasound is best for imaging the female reproductive organs and is much less expenxive than a ct or mri.

Can a CT scan detect an ovarian cyst?

Can a CT scan detect an ovarian cyst?

Yes: Yes, if it is large enough. Ct will usually detect ovarian cysts 10mm or larger, but an ultrasound is a better way to evaluate the ovaries and does not utilize radiation.

Would an ovarian cyst show up on a pelvic CT scan?

Would an ovarian cyst show up on a pelvic CT scan?

See answer: While ct can certainly identify an ovarian cyst, usually endovaginal us is better suited for this purpose.

Ovarian cyst & retroperitoneal adenopathy on CT scan. What is survival time?

Depends: Survival time will depend upon what the diagnosis is. The ovarian cyst and the enlarged lymph nodes may be unrelated to each other. You need further evaluation and biopsy of the enlarged lymph nodes if appropriate.

Is it possible that a CT scan would miss the fact I may have had an ovarian cyst rupture?

Is it possible that a CT scan would miss the fact I may have had an ovarian cyst rupture?

Yes: Ct resolution has gotten better and better, and a ct scan with IV contrast can usually identify even small ovarian cysts. But if the ovarian cyst ruptures, the ovary usually looks fairly normal on ct. If it was a small cyst that ruptured, the amount of fluid in the pelvis may overlap with normal physiologic fluid. Only if the cyst was large and/or bleeding would the ct likely be diagnostic.

Can a CT scan tell u what type of ovarian cyst you have? Was diagnosed at ER with 3.6 CM cyst and followed up with gyno- she did no further tests

Differential: A CT scan can give you what doctors call a differential diagnosis of an ovarian cyst: it will limit the possibilities to a reasonable list of what it might be. No imaging study ever diagnoses 100% what an ovarian mass is.

A CT scan detected an ovarian cyst. Could this be causing my lighter than usual periods?

A CT scan detected an ovarian cyst. Could this be causing my lighter than usual periods?

Ovarian cyst: Ovarian cysts can be hereditary or from hormonal changes in your body. They do not directly affect your menses, so no is the answer.

Painful 3.6 CM ovarian cyst found using a CT scan at ER, no sono so ER and gyno I guess assumed its a follicle cyst, wait it out? Scared of rupture

Painful 3.6 CM ovarian cyst found using a CT scan at ER, no sono so ER and gyno I guess assumed its a follicle cyst, wait it out? Scared of rupture

Wait and see: That is a nice size cyst. Not uncommon however. And yes when they rupture there may be some pain. But everyone is different. Talk to your gynecologist to help with this issue

Will an ovarian cyst always show up on a CT scan?

See answer: Ultrasound or possibly MRI usually are used for evaluating specific ovarian pathology although ct can identify lesions of the ovary.

Why would ovarian cysts not show on ct scan when it showed on U/S the day before?

It depends: On how the CT was performed. And how big the cysts are. Transvaginal ultrasound has superior resolution to routine CT, so small cysts visible on US may be difficult or impossible to see on CT, particularly if the CT was performed without IV contrast.

What are bilateral ovarian cysts? I had CT scan and dr said I have these but no cause for concern. Can this affect my ability to conceive?

It depends: More than likely you have polycystic ovaries which can be common, but may cause problems over time. You might have a higher rate of infertility, irregular cycles and other symptoms related to this finding. If the cysts enlarge that can cause other issues that your gynecologist needs to follow. Get ultrasounds instead of ct scans in the future to follow these cysts decreasing radiation exposure.

There's blood in my urine. My CT scan just showed a "possible ruptured ovarian cyst." but now, I haven't had to go number 2 in days. Is this related?

There's blood in my urine. My CT scan just showed a "possible ruptured ovarian cyst." but now, I haven't had to go number 2 in days. Is this related?

Possibly: Sometimes blood in the urine can actually be coming from the rectum. If the doctor does a urinalysis and says there's blood in urine, then you can believe it. Blood from rectum due to constipation is way more common than blood in urine. Your ovarian cyst isn't related to possible blood in urine or rectum. I would take MiraLAX (polyethylene glycol) to help have bowel movement, and increase your hydration.

Ct scan showed free fluid from ruptured ovarian cyst follow up ultras showed pelvic fluild dr said no there was not a ruptured cyst how can they tell?

Ct scan showed free fluid from ruptured ovarian cyst follow up ultras showed pelvic fluild dr said no there was not a ruptured cyst how can they tell?

Cyst rupture or not?: The free fluid could be from a ruptured ovarian cyst, or it could just be physiological free fluid. Did you have severe pelvic pain that seemed to get better with time? If so, a ruptured cyst is more likely.

Have a ovarian cyst 8cm, on CT scan mesenteric and retroperitoneal lymph nodes noted? Does that mean enlarge? . I'm confused. It didn't say enlarged.

Have a ovarian cyst 8cm, on CT scan mesenteric and retroperitoneal lymph nodes noted? Does that mean enlarge? . I'm confused. It didn't say enlarged.

Not necessarily: 8cm cyst (depending on what it looks like on the scan) does not have to be cancer in someone your age. Lymph nodes are often visible on scans and as long as they are not enlarged (greater then 1cm) they are just a normal finding. The cyst should be followed up on in a short period of time (6weeks) with a pelvic ultrasound, but if there was anything questionable about the lymph nodes then ct.

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! The image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
