Question 1

can hiatal hernia be missed on ct scan?

Accepted Answer

Yes.: Small hiatal hernias may not be visible. Also many hiatal hernias are "sliding" so they may not be apparent when you're laying flat on your back. The best test other than endoscopy is an upper GI series for delineating hiatal hernias.

Question 2

can fibrosis be missed on ct scan and ultrasounds? im in tears gallbladder issues now im terrified?

Accepted Answer

Question 3

what are the symptoms of a pterion fracture? can a pterion fracture be easily missed by ct scan?

Accepted Answer

Variable: Could range from brief loss of consciousness to focal paralysis to focal hemorrhage causing brain herniation and death. Depends on effect of the fracture.  CT is a good tool to confirm

Question 4

could an internal hernia, in the mid-abdomen, be missed on ct scan? is mri more accurate?  thank you.

Accepted Answer

No: An internal hernia can only be suspected post surgery when signs of partial bowel obstruction develops due to a loop entering a defect in mesentery or equivalent and bowel dilatation develops which can be defined by both CAT and MRI

Question 5

how reliable is a ab ct scan for colon cancer? had 3, what percentage of cancers are missed in a ct scan? trying to find stats.

Accepted Answer

Not good: This same question has been asked several times today. A ct scan will not see a colon cancer unless it is large enough and advanced enough so that it could then be seen. Colonoscopy will see a colon cancer at a much earlier stage. I know of no statistics for what you are asking.

Question 6

can ct scan miss stones?

Accepted Answer

Yes.: It depends on the composition of the stone. Gallstones are usually cholesterol and may not be calcified. Tiny urate renal stones may alson not be seen.

Question 7

can a ct scan miss an aneurysm?

Accepted Answer

&lt; 1 cm, yes: The size matters-- &lt; 1 cm and ct may miss it.  Ct w/ 3d reconstruction is markedly improved imaging technique, but this specific test needs to be requested before hand...

Question 8

can a concussion be missed even after a ct scan?

Accepted Answer

Clinical diagnosis: A concussion is a clinical diagnosis, or signs/symptoms not seen on a ct scan. A ct scan shows bleeding (hemorrhage, hematoma), brain without enough blood flow (infarct) or fractures (breaks in bone). It might show contusion or swelling (edema). But usually with a concussion (altered mental status, possible visual changes, dizziness), you have a normal ct scan.

Question 9

docs, could a ct scan miss pheochromocytoma?

Accepted Answer

No: No pheos are defined because one is looking for cause of hypertension and blood tests indicate tumor producing adrenaline line hormones is the cause.  A pheo at 2 cm. can easily be defined.  Many of these lesions even reach 10-15 cm. when first detected.

Question 10

can ct scan miss mass in the abdomen?

Accepted Answer

Varies widely...: The sensitivity (how likely to be detected) of abdominal ct scans for abdominal masses varies widely depending on the type of abdominal mass and the abdominal ct technique. When both oral and intravenous contrast are used, the sensitivity is much higher (up to 90% for some masses). However, some masses are still difficult to detect and have lower sensitivity such as colonic and small bowel masses.
