Gray Scale Ultrasonography and Colour Doppler Study in Fracture Healing

Background: Traditionally acute scrotal pain is evaluated by gray scale ultrasound, which dissipated only the morphological changes of the lesion. But pattern of vascularity either normal, increased or absent of affected structure help to definitive diagnosis of the lesion and help to proceed the type of management either medical therapy or surgical treatment.Objectives: To determine the relative importance of color Doppler in the evaluation of acute scrotal pain by ultrasound.Methods: From June 2013 to June 2017 a total 150 patients with acute scrotal pain were selected. A thorough history taking and physical examination were done. Then patient were scanned with gray scale ultrasound followed by color Doppler study. Color Doppler diagnosis is compared with gray scale diagnosis.Results: In gray scale ultrasonography among the 150 cases, 54% were diagnosed as epididymitis, 16.66% were epididymo-orchitis and 16% patient diagnosed as normal. But in combined gray scale and colour Doppler study 58% were diagnosed as epididymitis, 22% were epididymo-orchitis and 6% of patient diagnosed as normal. In gray scale 10% patient were diagnosed as normal but become epididymitis and epididymo-orchitis in colour Doppler. Four percent were diagnosed as epididymitis in gay scale but became epididymo-orchitis in colour Doppler. Four percent patient was diagnosed as epididymitis orchitis but became testicular torsion in Doppler study. Total 14.66% of gray scale diagnosis became another diagnosis in the Doppler study.Conclusion: Combined gray scale and color Doppler study is superior than gray scale ultrasound in differentiating various cause of acute scrotal pain.Bang Med J (Khulna) 2017; 50 : 26-30

Optimal Site

While ultrasonography is widely performed prior to biopsy, colour Doppler examination is often used only to discover post-biopsy complications. Aim of this paper was to evaluate the usefulness of colour Doppler examination in planning the optimal site of puncture for renal biopsy. Present analysis includes 561 consecutive percutaneous renal biopsies performed from the same operator. Until August 2000 332 biopsies were performed after a preliminary ultrasonography (Group A). From September 2000, 229 patients underwent even a preliminary colour Doppler study (Group B). Postbioptic bleeding were categorized as minor (gross hematuria or subcapsular perinephric hematoma < 4 cmq of greater diameter) or major (hematoma >4 cmq of greater diameter; requiring blood transfusion or invasive procedures; leading to acute renal failure, urine tract obstruction, septicaemia, or death). Major complications were seen in 2.1% in Group A while in Group B only one case was reported (0.43%). Minor clinically significant complications occur in 7.8% in Group A and in 3.4% of cases of Group B. Colour Doppler reduced drastically the incidence of complications observed before the introduction of routine colour Doppler examination prior to biopsy. In our opinion, these data support the use of preliminary colour Doppler study when a biopsy is planned.

Doppler Study

Introduction: Cervical region is the commonest area of lymphadenopathy which is easily accessible to ultrasound and Doppler study. The morphological and vascular-architectural differences among various nodal diseases aids in differentiating benign from malignant causes. Methods: The study was done on the 108 patients referred to Department of Radiology andImaging, TUTH for ultrasound of cervical lymphadenopathy who subsequently underwentFNAC examination. Gray scale evaluation for morphology of the nodes along with Doppler evaluation for resistive index (RI), pulsatility index (PI) and Peak systolic velocity (PSV) were done and correlated with FNAC findings. Results: Among the 108 lymph nodes, 24 were proven to be malignant on FNAC. Features such as S/L ratio >0.5, absence of echogenic hilum, and abnormal vascular pattern demonstrated sensitivities of 96%, 92%, and 87%, specificities of 74%, 65% and 77% and positive predictive values (PPVs) of 51%, 43%, and 55% respectively. The cutoff values for RI, PI and PSV were found to be 0.705, 1.34 and 17.5 cm/s with sensitivities of 96%, 96% and 87%, specificities of 95%, 99% and 88% and positive predictive values (PPVs) of 85%, 95% and 70% respectively. Conclusion: Ultrasound findings of S/L ratio, absence of echogenic hilum, abnormal vascular pattern and Doppler indices revealed good sensitivity, specificity, and accuracy in differentiating benign and malignant lymph nodes.
