VUJ-calculus

Left VUJ calculus with twinkle sign on colour Doppler.

Femoral-vein-thrombosis

Common femoral vein thrombosis following  sclerotherapy in adult male. Non
compressible on probe pressure.
Absent flow on spectral Doppler ultrasound.

MNG-or-multinodular-goiter

Multinodular goiter is a common finding on sonography.
In this case there are both cystic and solid lesions in the right lobe of thyroid with extensive calcification of one of the nodules. The left lobe of thyroid shows a thick walled large cyst occupying most of the lobe. Multiple vascular intramural nodules are also seen in the cyst with considerable vascularity of these nodules.
Thyroid malignancy is highly likely in this situation.
The sonologist must look for potential sites for malignancy in any case of multinodular goitre.

Phyllodes-tumour-3D-ultrasound

Left breast mass large one 36 years female.
Leafy pattern in mass with vascularity.
S/o phyllodes tumour.

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.
