Overview
Organ | Disease | CT | SONO |
---|---|---|---|
Gastrointestinal system | Intestinal pseudo-obstruction |
|
|
Hepatitis |
|
||
Acute pancreatitis | Abnormalities that may be seen in the pancreas include:
|
| |
Autosplenectomy |
|
Ultrasound will either not be able to demonstrate a spleen at all, or identify a small irregular and shadowing nodule in the splenic bed. | |
Mesenteric vasculitis |
|
||
Acute cholecystitis |
|
| |
Pulmonary involvement | Pleural effusion |
|
echo-free space between the visceral and parietal pleura |
Pulmonary emboli |
|
||
Pulmonary hypertension |
|
||
Shrinking lung syndrome |
|
||
Pulmonary fibrosis |
|
||
Pneumonitis |
|
||
Cardiac involvement | Mitral stenosis |
|
|
Acute pericarditis |
|
||
Pericardial effusion |
|
Echocardiography is the method of choice to confirm the diagnosis, estimate the volume of fluid and most importantly assess the haemodynamic impact of the effusion | |
Coronary artery disease |
|
||
Neurological involvement | Genreral |
|
|
Stroke |
|
||
Raynaud phenomen | Doppler sonography:
flow volume and vessel size irregularities |
