Background: Characterization of ovarian masses is essentially required and inevitable for optimization of clinical decision making, patient care and management. The diagnosis of ovarian masses is a frequent dilemma in clinical work. Ultrasonography remains the modality of choice in the early investigation of suspected adnexal masses because of its availability and being a safe modality. Aim: To review the current literature on different patterns of manifestation of ovarian masses on ultrasound and its various modes, helping in differential diagnosis on the basis of morphologic, vascular and other characteristics as seen on ultrasound. Methods: Electronic database was searched (PubMed, Google Scholar, Science direct) with data ranging from year 2000 to 2021. Most relevant studies, relating to sonographic appearances of ovarian masses were selected. Results: Twenty five most relevant articles were found: 8 articles were regarding gray-scale ultrasound, 3 articles regarding three dimensional ultrasonography, 2 articles regarding contrast enhanced ultrasonography, 2 regarding elastography and rest were regarding combined use of gray-scale and Doppler ultrasound including color and power Doppler ultrasonography for the assessment of ovarian masses. Our results show that conventional 2D sonography, in conjunction with latest advancements helps improving the diagnosis based on typical sonographic appearances of masses. Screening for ovarian cancer also proves to be helpful for early diagnosis and improvement in survival rate. Conclusion: Ultrasonoraphy and its different modalities such as 3DUS, CEUS, elastography along with conventional 2D and Doppler studies accurately identifies morphologic, structural and vascular featuresof the adnexal masses and differential diagnosis by escapingunnecessary surgeries and improving the survival rate.

Objectives: To compare the diagnostic accuracy of transabdominal ultrasonography and contrast enhanced magnetic resonance imaging, in the differentiation of benign and malignant adnexal masses. Study Design: A prospective comparative study. Place and Duration of Study: Armed Forces Institute of Radiology and Imaging (AFIRI), Rawalpindi from 16 Jun 2015 to 15Jun 2016. Methodology: 61 female patients with adnexal masses, irrespective of age, were evaluated with transabdominal ultrasonography and contrast enhanced magnetic resonance imaging (MRI). This was followed by surgery (either laporotomy or laproscopy) or ultrasound guided biopsy and then histopathology to characterize them as benign or malignant masses. Results: Diagnostic accuracy of contrast enhanced MRI for characterization of adnexal masses was 90.1%, while that of transabdominal ultrasonography was 72.1 %. Sensitivity and specificity of transabdominal ultrasonography was 100 % and 54 % respectively while positive predictive value was 58.5 % and negative predictive value was 100 %. Sensitivity and specificity of MRI was 95.8 % and 86.4 % respectively while positive predictive value was 82.1% while negative predictive value was 96.9 %. Conclusion: Contrast enhanced MRI has a superior diagnostic accuracy as compared to transabdominal ultrasonography in the characterization of adnexal masses into benign and malignant, which influences the mode of treatment and clinical outcome.

Abstract Lameness is a serious health concern for livestock species. Understanding individual animal response to pain and characterization of lameness are critical when developing appropriate treatments. The objectives of this pilot study was to evaluate two different lameness models and measures for determining response to induced lameness in meat goats. Lameness was induced by intraarticular injection into the left hind lateral claw distal interphalangeal joint with either amphotericin B (Amp-B) or kaolin-carrageenan (K-C). Response to lameness was characterized by behavior scoring, visual lameness scoring (VLS), infrared thermography (IRT) of the affected digit, pressure mat gait analysis (PMT), and plasma cortisol (CORT) analysis. Lame goats had higher VLS compared to controls (P = 0.003). Maximum temperatures measured in hooves from lame vs control goats were significantly higher (P = 0.003). Pressure mat analysis demonstrated, when compared to controls, lame goats had decreased force (P = 0.013), impulse (P = 0.007), contact pressure (P = 0.007), and contact area of the left hind limb (P = 0.009). Mean CORT levels 4 and 6 h after lameness induction were higher in lame goats (P = 0.005, P = 0.01). The two lameness methods reliably induced lameness of varying severity in healthy meat goats.

Abstract Purpose Renal lesions are frequent random findings on CT, MRI, and conventional ultrasound. Since they are usually found accidentally, the respective examinations have not been performed optimally to provide a conclusive diagnosis, making additional multiphase contrast-enhanced examinations necessary. The aim of the study is to correlate CEUS findings with the final diagnosis and to determine whether it is a suitable method for the conclusive characterization of undetermined renal lesions. Materials and Methods All CEUS examinations of focal renal lesions performed at our institute between 2007 and 2014 were retrospectively examined. 437 patients with a total of 491 lesions and 543 examinations were included. 54 patients had bilateral lesions. One patient had three lesions in one kidney. Histology was available in 49 cases and follow-ups in 124 cases. The sensitivity, specificity, positive and negative predictive value as well as positive and negative likelihood ratios were calculated. Results There were 54 malignant and 437 benign lesions. The sensitivity and specificity were 0.981/0.954 overall, 1.000/0.956 for cystic lesions, 0.977/0.906 for solid lesions, and 0.971/0.071 for the histologically confirmed lesions. Bosniak classification was consistent in 289 of 301 lesions (96%). Only 12 lesions (3.9%) were falsely assessed as malignant. Conclusion CEUS is an appropriate method for the clarification of undetermined renal lesions. The characterization of cystic lesions according to Bosniak is adequately possible, especially for potentially malignant lesions (types III and IV).
