Renal transplant complications, role of resistive index on colour doppler ultrasound

We evaluated 50 patients who had renal transplants and were sent for Doppler Ultrasound for complications, after the transplant procedure. Ages of the patients ranged from 20 to 65 years, 39 were male and 11 were female. In inclusions only first month post op patients were included and only those patients were considered who had some sort of complications on ultrasound at some stage of the follow up.Following complications were noticed: Diminished corticomedullary demarcations, increased echogenicity with raised R I [20 pt]. Perinephric collections other than haematoma [13 pt]. Perinephric haematoma [06 pt]. Obstructed transplanted kidney [05 pt]. Diminished arterial vascularity of the kidney [04 pt] Renal vein thrombosis [02 pt]. RI was found to be raised in increased echogenicity, obstructed hydronephrotic kidney, diminished arterial supply and was disturbed in RVT

Doppler evaluation of breast solid masses differentiation of benign and malignant masses role of resistive index

To know the usefulness of color and spectral doppler in evaluation of solid breast masses using vascularity and resistive index. We performed duplex doppler sonography on 100 patients presenting with breast mass. Resistive index and vascularity of the vessels were detected and analyzed and correlated with histopathological results. 70% of the benign lesions were found having ri below 0.8 and 45 out of 50 patients had low vascularity.43 malignant lesions had high vascularity and 80% had ri above 0.8. High flow visualization on power doppler and indicates a higher possibility of malignancy lesions with ri greater than 0.8 gives high probability of malignancy

it aleays DVT? evaluation of leg swelling with color doppler sonography

The aim of this study was to assess the value of duplex ultrasound examination in establishing diagnosis in swollen lower limbs. This study was conducted at the Department of Diagnostic radiology Mayo hospital Lahore. 50 consecutive patients presenting with leg swelling, submitted for colour Doppler sonography of the lower extremities were examined for deep vein thrombosis [DVT]. 46% of the patients were detected as having DVT, when examined through Doppler Ultrasonography. While 28% of the patients were not having any pathology in the limb.26% of the patients were having pathology other than DVT. The veins of the calf muscles are a common site of acute DVT and a source of pulmonary embolism. They should always be investigated in patients with leg swelling. Complete venous evaluation with duplex imaging can be very helpful in determination of underlying cause of the swelling
