Abstract Background The ulnar artery perforator (UAP) flap, which is hairless, thin, and pliable, has been used for the reconstruction of soft tissues from the finger to the elbow. Preoperative planning is essential for a perforator flap surgery, and there are some tests to identify perforators. Color Doppler ultrasonography (US) with a high-frequency transducer helps in detecting decreased flow in smaller vessels, such as perforators. The purpose of this study was to determine the anatomical locations and origins of perforators arising from the ulnar artery using color Doppler US in healthy volunteers. Methods Forty forearms of 20 healthy volunteers were included in the study. Perforators arising from the ulnar artery, within 100 mm proximal to the pisiform, were investigated using color Doppler US with a high-frequency transducer. Results A total of 205 perforators were identified. On comparing the locations in each 20 mm section from the pisiform, the largest number of perforators was 58 (28%), within 20 mm proximal to the pisiform. The axial view demonstrated 44 (21%), 64 (31%), 32 (16%), and 65 (32%) perforators in the radial, ulnar, superficial, and deep aspects of the ulnar artery, respectively. Fifty-two and 28 essential perforators were supplied by the UAPs arising from the superficial and ulnar aspect within 20 mm proximal to the pisiform and between 21 and 40 mm proximal to the pisiform, respectively, while elevating the UAP flap. Conclusion This is the first study to assess the UAP using color Doppler US. Identification of UAP using color Doppler US can be used as a preoperative assessment for reliable elevation of a UAP flap.

Objective: To investigate the diagnostic value of color Doppler ultrasonography in detecting calcifications in thyroid nodules for benign and malignant thyroid nodules. Methods: This study selects 108 patients with thyroid nodules who underwent color Doppler ultrasonography at designated hospitals from June 2013 to June 2018 as study subjects, retrospectively analyzes their general patient data, preoperative color Doppler ultrasound data and postoperative pathological diagnosis results, and discusses the diagnostic value of calcification rate, calcification type and calcification characteristics for benign and malignant thyroid nodules. Results: The results show that preoperative color Doppler ultrasonography found 112 thyroid nodules in 108 patients, including 72 benign nodules and 40 malignant nodules; pathological analysis confirmed 124 thyroid nodules, including 78 benign nodules and 46 malignant nodules; the diagnostic coincidence rate of color Doppler ultrasound is 90.32% (112/124), the misdiagnosis rate is 9.68% (12/124), the specificity is 86.94%, and the sensitivity is 81.27%; in these 112 thyroid nodules, 89 nodules were calcified accounting for 79.46%; in 72 benign nodules, 13 nodules were calcified accounting for 18.06%; in 40 malignant nodules, 17 were calcified accounting for 42.50%; the calcification of malignant nodules was significantly higher than that of benign nodules; in 72 benign nodules, 6 cases is coarse calcification accounting for 8.33%, 3 cases is cyclic calcification accounting for 4.16%, and cyclic and coarse calcification are only 23.46% sensitive to thyroid cancer; in 40 malignant nodules, 3 cases is coarse calcification accounting for 7.5%, and 2 cases is cyclic calcification accounting for 5.00%. Conclusions: According to the analysis, the calcification in thyroid nodules has relatively high sensitivity and specificity for the diagnosis of benign and malignant nodules and it can be used as a specific index for screening thyroid cancer.

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.
