Acute-appendicitis

Acute appendicitis typically shows:
Increased diameter > 5 mm ( here it is 8 mm).
Increased vascularity
Hypoechoic collection within
Typical gut signature
Blind ending tubular structure

Medical-renal-disease

Patient with high serum creatinine.
Echogenic kidneys with loss of cortico-medullary differentiation.
Medical renal disease.

IUGR-fetus-32-weeks

This fetus shows IUGR or intrauterine growth retardation.
-By biometry fetal age is 29 weeks as opposed to 32 weeks by LMP.
- fetal AC= 26 weeks
In addition color and spectral Doppler studies show:
- high resistance flow in Uterine artery- RI > -0.7 (normally < 0.5)
diastolic notching
- MCA--> low resistance flow with RI< 0.6
-Umbilical A. shows RI > 0.8 (high resistance flow)
- cerebroplacental ratio is reversed with = 0.6/0.8= 0.7 (normally should be > 1)
- fortunately no reverse diastolic flow is seen in umbilical artery or uterine artery
and near normal ductus venosus flow
diagnosis: IUGR with moderate fetal hypoxia.

Ureteral-calculus-stenting

Distal Rt. ureteral calculus nearly at the right vesico-ureteral junction was removed.
The calculus is seen below with moderate right hydronephrosis:

Bladder shows DJ ureteral stent lower tip (3D ultrasound image) which was inserted after surgical removal of the calculus.
The upper end of the stent is seen in right renal pelvis.
Observe reduction in hydronephrosis.
