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.

Background: Duplex Colour Doppler Sonography is gaining increasing popularity for assessment of blood vessels in various disease processes around the world as well as for the surveillance of fetus compromised by intra uterine growth retardation (IUGR) and to assess foetal structural abnormalities and complex disease processes. Materials & methods: This cross sectional study was carried out to observe Doppler wave form in subjects with preeclampsia enrolling 40 subjects with preeclampsia, in the Department of Radiology and Imaging, Dhaka Medical College Hospital, Dhaka, over a period of six months from 20th May 2012 to 19th November 2012. A total number of 40 normal pregnancies were also included for comparison. Peak systolic velocity (PSV), end diastolic velocity (EDV), Resistive index (RI), Pulsatility index (PI) in different groups of study subjects from 24th to 37th weeks were observed and compared for any significant differences. Results: Majority (35% in normal and 37.5% in preeclampsia) of the respondents were found in the age group of 21-30 years. Unpaired t-test revealed no significant difference between mean age between two groups. Among normal group, mean±SD PSV, EDV, PI and RI were 43.94±15.41 cm/sec and 15.51 (±4.93) cm/sec, 1.12±0.0846 and 0.571 (±0.058) respectively. Mean PSV, EDV, PI and RI were 83.19±18.44 cm/sec, 11.86±5.19 cm/sec, 2.497±0.369 and 0.8255±0.087 in preeclampsia group. There was statistically significant (By unpaired ttest) difference in mean Doppler indices between these two groups. It was observed that early diastolic notch was found in 90% subjects with preeclampsia. Early diastolic notch was observed in Doppler wave form in 5% subject with normal pregnancy. Chi-square test showed that there was statistically significant difference in presence of early diastolic notch between normal subjects and subjects with preeclampsia. Conclusions: From the study result it was concluded that Doppler indices with presence of early diastolic notch are reliable indicators for early detection of preeclampsia.

Inguinal Herniotomy

Background Knowing transient vascular perfusion abnormalities of testes after open inguinal herniotomy procedure is essential for the surgeon who is mainly responsible for the patient outcome. Purpose To assess the effect of open inguinal herniotomy procedure on the testicular blood supply in children using duplex ultrasonography (DUS). Material and Methods A prospective observational study included 60 boys (mean age = 9.46 ± 14.46 months; age range = 2 months–6 years) who underwent open inguinal herniotomy operation. Using DUS, the testicular volume, peak systolic velocity (PSV), end diastolic velocity (EDV), and resistive index (RI) were calculated preoperatively and one week, one month, and six months postoperatively. The pre- and postoperative measurements were compared. Statistical analysis was performed using χ2 test, Fisher’s exact test, or Student’s t-test when appropriate. Results On physical examination, the hernias were unilateral in 57 boys and bilateral in three boys. Comparison between testicular volumes preoperatively and postoperatively showed no significant change ( P > 0.05). There was a statistically significant increase of PSV and RI one week and one month postoperatively ( P < 0.0001) but returned to be near to the preoperative values at six months. As regards EDV, there was a slight but non-significant postoperative increase ( P > 0.05) which did not return to the preoperative value. Conclusion The affection of testicular vascularity postoperatively is transient and returns to be near to the preoperative values in the late postoperative period (six months postoperatively). Additionally, no significant change in testicular volume postoperatively.

Haemodynamic Changes

Introduction: Varicocele is among the most frequently encountered, surgically correctable causes of male infertility. Since varicocele is a primary abnormality of testicular vessels, a thorough understanding of haemodynamic changes in the microcirculation of varicocele testis is needed. Objectives: To estimate changes in the microcirculation of varicocele testis and correlate them with symptomatic and semen parameters changes before and after varicocelectomy. Material and methods: This prospective, observational study includes 47 patients of age group 18–40 years who underwent microsurgical varicocelectomy during June 2016 to April 2018 at a tertiary medical institute. Testicular haemodynamic was evaluated using a colour spectral doppler study (PSV-Peak systolic velocity/ESV-End diastolic velocity/RI-Resistive index/PI-Pulsatility index). Semen analysis parameters and testicular blood flow were compared with pre-operative values. Results: RI in the capsular artery of varicocele affected testis, which was 0.61 ± 0.11 (mean ± SD), significantly reduced to 0.56 ± 0.09 (mean ± SD) in post-operative follow-up, indicating improved perfusion. Pre-operative sperm density was noted to be 15.94 ± 7.88 (mean ± SD), which improved to 28.41 ± 10.99, Progressive sperm motility from 33.81 ± 10.88 to 38.32 ± 9.21 and morphology from 36.13 ± 10.68 to 41.43 ± 9.29 on 6-month follow-ups ( p < 0.05). Conclusion: Varicocele testis is associated with altered testicular haemodynamic, which insults spermatogenesis. Microsurgical varicocelectomy with testicular artery and lymphatic preservation leads to correction of this altered haemodynamic state and improves the testicular microcirculation.

Introduction: Color Doppler Imaging (CDI) is used widely to study retrobulbar circulation. Objectives: To determine the association between progression of diabetic retinopathy (DR) and alterations in retrobulbar arterial circulation using CDI studies. Materials and methods: Prospective observational case series. It is single institutional study of 50eyes of nonproliferative diabetic retinopathy in 50 patients with type II diabetes mellitus. DR was graded according to ETDRS system. Retrobulbar circulation was studied in patients for Peak systolic velocity (PSV), End diastolic velocity (EDV) and Resistive index (RI) in Central retinal artery (CRA), Ophthalmic artery (OA) and Posterior ciliary artery (PCA) using CDI initially and reevaluated after 6 months or later for any change in retinopathy grade and arterial circulation parameters. The patients were grouped as Group I not showing progression of DR and Group II showing progression. The two groups were compared for any significant change in CDI parameters. Results: The baseline resistive indices were higher than normal population. There was significant increase in RI in PCA and CRA in all patients after 6 months. 14 patients (28%) showed progression of DR and 36 (72%) did not show progression of DR. There was no significant association with progression of retinopathy and CDI findings. (p=>0.05). Conclusion: The retrobulbar arterial circulation seems to be affected in all diabetics with DR. The changes appear to be progressive. The CDI findings in arterial circulation however lack predictive power for progression of diabetic retinopathy in non proliferative DR.

Purpose: to investigate the utility of the resistive indices (RIs) of the epididymal and intratesticular arteries, and to establish diagnostic criteria for scrotal inflammatory disease on the basis of quantitative color Doppler sonography Material and Methods: We prospectively examined 29 consecutive patients with scrotal pain, and 15 normal control subjects. the RIs of the intratesticular and epididymal arteries were obtained from color Doppler sonographs Results: the RIs of the testicular artery in epididymoorchitis were significantly lower than those in normal control subjects and in epididymitis (p<0.01) while the RIs of the testicular artery in epididymitis and control subjects were similar (p>0.5). with a cut-off value of RI=0.5, sensitivity, specificity, accuracy, and positive and negative predictive values were 91%, 94%, 94%, 83%, and 77% respectively. the mean RI of the epididymal arteries in epididymitis and epididymoorchitis was 0.49±0.11. A high level of diagnostic accuracy in scrotal inflammatory disease was achieved when the RIs of the intratesticular and epididymal arteries were less than 0.5 and 0.7 respectively Conclusion: the RI of the intrascrotal artery would give a more objective evaluation than subjective assessment and could provide diagnostic criteria for scrotal inflammatory disease

INTRODUCTION: Ultrasonography is extremely well suited to study of scrotum and its contents. Ultrasound is simple to perform, quick, non-invasive, low cost effective, easily reproducible, widely available and does not involve irradiation of gonads.It is very helpful in differentiating intratesticular and extratesticular pathologies. Ultrasound is the modality to differentiate solid from cystic lesions of testes and with the introduction of color Doppler, it becomes easiear to assess the viability of testis in cases of torsion and guiding the treatment accordingly. USG is helpful in differentiating torsion/ischaemia of testis from the acute inammatory pathologies. Role of other Modalities: CT and MRI have dominated imaging of other regions of the body, they have certain restrictions in evaluation of scrotal diseases. Computed Tomography delivers radiation to gonads, On the contrary, MRI imaging is expensive and not readily obtainable. Radionuclide scan helps in equivocal presentations to assess vascularity within the testis in setting of torsion but its readily availability and cost is the main set back. AIM: To assess the role of high frequency gray scale and color doppler ultrasonography in evaluation of epididymorchitis. MATERIAL & METHODS: SAMPLE: 50 cases of scrotal pathology were taken using High-frequency real time gray scale ultrasonography and Color Doppler . Patients were referred to our department for scrotal ultrasonography and Doppler study by department of Urology and department of Surgery of SRMS IMS Bareilly. RESULTS: In the present study total evaluated cases of epididymoorchitis were 15,among them 11 cases were acute and 4 cases were of chronic epididymoorchitis.. Majority of cases were having unilateral involvement with 1 case of B/L involvement. USG gray scale found heterogenous echogenicity or reduced echogenicity in acute EPO while the echogenicity was reduced with calcication in chronic EPO. .Doppler study found increased vascularity in majority of cases of acute EPO with reactive hydrocele while vascularity was either normal or increased in chronic EPO without any reactive hydrocele. CONCLUSION: High-frequency gray scale USG helps in clear evaluation of anatomical structural alterations associated with acute scrotal inammatory diseases, and color Doppler USG is highly sensitive in diagnosing acute scrotal pathology. In addition, Color Doppler USG accurately differentiates between testicular ischemia and torsion from acute inammatory diseases in acute painful scrotal conditions.

Acute Scrotal Pain

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
