Appendix CT Scan Normal Vs Appendicitis Images | Acute, Gangrenous Types & Perforated Appendix
*Cases
Acute Appendicitis - 0:00
Caecal Bar Sign - 3:44
Arrowhead Sign - 4:07
Gangrenous Appendicitis - 7:49
Perforated Appendicitis - 8:57
Normal Appendix:
Diameter less than 6mm
Normal fat around the appendix appears hypodense (dark) and homogeneous
Acute Appendicitis:
Dilated fluid-filled appendix (Diameter more than 6mm)
Appendicolith: Hyperdense (bright) structure within the appendix
The normally homogeneous, low-density fat tissue around the appendix appears more dense (brighter) and heterogeneous.
Gangrenous Appendicitis:
Parts of the wall may show lack of enhancement after contrast administration
More extensive and intense fat stranding
Gas formation within the appendix due to gas-producing bacteria involved in the infection.
Perforated Appendicitis:
Focal appendiceal wall defect
Extraluminal gas
Periappendiceal inflammation
Periappendiceal Phlegmon: Severe inflammation with extensive fluid collection. Usually has higher density (appears brighter) than abscess. Has ill-defined borders
Abscess: Has lower density (appears darker) than a phlegmon. Has a clear border or a wall, which may enhance after the administration of contrast material, indicating an inflammatory response.

Pls do more of ct imaging videos

[@ChrisBrown-qx6my]

Thank you for the fantastic detail and information. I have the CT scans from my burst appendix but have no idea what I'm looking at. At least now I know (kinda) what I should be looking for (just for curiosity sake). Have a great day!

Thank you sir for sharing this information , would you please help us finding the SMV and IMA during portal vein Doppler?

[@DrSamsImagingLibrary]

Thanks for watching and for the suggestions!

I was operated 3 weeks ago: so-called "silent appendicitis" (no fever, tolerable pain, mild leucocitosis, CRP through the roof) perforated, with peritonitis. I have looked at my CT scan like 15 times and cannot find the damn appendix

[@lazarsajcic9784]

Did they try first with antibiotics? I think I have same thing.. my CT scan show nothing 2 days ago , but still feel that right abdominal side

[@jaimetorres950]

@@lazarsajcic9784 In my case, there was no way of trying first with antibiotics: The CT scan clearly showed the ruptured appendix + peritonitis. So I was immediately wheeled to surgery. But I have read that in some cases antibiotics are being tried initially w/o surgery

Hello, Are this İmages with contrast ? I can't understand the difference between contrast and non-contrast? Thanks for the video

[@DrSamsImagingLibrary]

Hi! The first image and the third image in arrowhead sign are non contrast images. The rest are contrast enhanced images. When you see bright (enhanced) arteries (aorta etc.) and intestines, they are contrast enhanced. When they are greyed out, the image is without contrast.

[@zohebmulla3670]

Colon or large intestine ulcers can be detected in ct scan?

[@DrSamsImagingLibrary]

Yes, CT scans can be used to detect ulcers in the colon or large intestine, although it is not the first choice modality. Colonoscopy is much more preferred for this.

​@@DrSamsImagingLibraryok sir thank u so much😊🙏🏻

Cut off for appendix on ct is 10mm

[@lazarsajcic9784]

Hello sir , 5 day's ago I felt pain in right side of abdomen I did CT scan next morning and first report was "Inflammatory changes in the right iliac fossa with slight enhancement at the proximal appendix. Features my represent mild appendicitis change" they keep me hospitalised give me 12 doses of antibiotics through IV and yesterday morning repeat CT scan and report was "Normal abdomen structure" But my pain is same I have CD with myself. Don't know what to do

[@DrSamsImagingLibrary]

Please follow up with your doctor. Sometimes, mild appendicitis can persist despite initial antibiotic treatment. It may require more time for the inflammation to subside completely. Persistent pain should be thoroughly evaluated.

[@wonderfulworld1128]

Sir I'm very very confused. When we see the real human anatomy, the right and left organs in anatomy is in its normal and in fixed position but why the organs of right side shifted to the left side and left side organs to the right side position in CT scan. Please sir clear this concept by making a video please 🙏 sir.

[@DrSamsImagingLibrary]

This orientation is based on the standard radiological convention, often referred to as the "radiological view". The images are oriented as if the viewer is standing at the patient's feet, looking towards the patient's head. So, what is on the viewer's left is the patient's right side, and what is on the viewer's right is the patient's left side. This perspective is consistent across most types of radiological images. In the past, radiologists would hold up a film against a light box, and the orientation would be as if looking at the patient from the feet end. This convention has been carried over to modern imaging techniques.
