Surgical management of a diseased thyroid depends on sonological and pathological evaluation and thereby, planning of the surgery. The definite surgery has two objectives: removal of the diseased gland and preservation of the nerves, namely EBSLN (External Branch of Superior Laryngeal Nerve) and RLN (Recurrent Laryngeal Nerve) and the Parathyroid glands. The objectives of the study were: (1) To identify the course of the RLN and EBSLN of both sides, during Thyroidectomy. (2) To discern various anatomical landmarks, the relations of the two nerves with them and anatomical variations, if any...

INTRODUCTION: Hyperandrogenemia is the defining feature of polycystic ovary syndrome (PCOS). Increasingly androgens are being advocated to be measured through liquid chromatography-mass spectrometry (LC-MS/MS). The role of LC-MS/MS over immunoassay in diagnosis of PCOS has been debated over a long time. We analyzed the role of androgens as measured by LC-MS/MS in diagnosing women with PCOS. MATERIALS AND METHODS: We performed a prospective case-control study involving 59 women with PCOS compared with 30 age- and BMI-matched controls...

Nonmass lesions (NMLs) on breast US are defined as discrete areas of altered echotexture compared to surrounding breast tissue and lack the 3-dimensionality of a mass. They are not a component of American College of Radiology BI-RADS, but they are a finding type included in the Japan Association of Breast and Thyroid Sonology lexicon. Use of the NML finding is routine in many Asian practices, including the Samsung Medical Center and Seoul National University Hospital, and their features and outcomes have been investigated in multiple studies...

Abnormalities on breast ultrasound (US) images which do not meet the criteria for masses are referred to as nonmass lesions. These features and outcomes have been investigated in several studies conducted by Asian researchers. However, the term "nonmass" is not included in the American College of Radiology (ACR) Breast Imaging Reporting and Data System (BI-RADS) 5th edition for US. According to the Japan Association of Breast and Thyroid Sonology guidelines, breast lesions are divided into mass and nonmass...

AIMS: The present study seeks to investigate the correlation of pubofemoral distances (PFD) to α angles, and hip displaceability status, defined as femoral head coverage (FHC) or FHC during manual provocation of the newborn hip < 50%. METHODS: We retrospectively included all newborns referred for ultrasound screening at our institution based on primary risk factor, clinical, and PFD screening. α angles, PFD, FHC, and FHC at follow-up ultrasound for referred newborns were measured and compared using scatter plots, linear regression, paired t -test, and box-plots...

BACKGROUND: Pleiotropic effects of statins may be beneficial in alleviating cerebral vasospasm (VS) and improving outcome after aneurysmal subarachnoid hemorrhage (aSAH). Initiation of statin treatment at aSAH is not recommended; however, the effect of pre-ictal and continued statin use is not fully investigated. METHODS: Retrospective study comparing aSAH patients admitted in 2012 to 2021 with pre-ictal statin use versus those not using statins. Patient entry variables, radiological/sonological VS, symptomatic VS, and radiologically documented delayed cerebral ischemia (DCI) were registered...

BACKGROUND AND AIMS: Though the role of fasting preoperative gastric ultrasound has been validated in different patient populations, namely, obese, pregnant and diabetics, it has not been explored in patients with chronic kidney disease (CKD). This prospective, observational study compared the fasting sonological assessment of gastric contents in patients with CKD versus those with normal renal function scheduled for elective surgery. METHODS: After ethical approval and trial registration were obtained, preoperative gastric ultrasound was done in 115 CKD patients and 115 with normal renal function...

BACKGROUND: An increasingly 24/7 connected and urbanised world has created a silent pandemic of noise-induced hearing loss. Ensuring survival to children born (extremely) preterm is crucial. The incubator is a closed medical device, modifying the internal climate, and thus providing an environment for the child, as safe, warm, and comfortable as possible. While sound outside the incubator is managed and has decreased over the years, managing the noise inside the incubator is still a challenge...

Ultrasound images of ductal carcinoma in situ (DCIS) show a wide range of variations from mass to non-mass lesions. This article describes the characteristics of ultrasound images of DCIS based on the BC-02 study conducted by The Japanese Association of Breast and Thyroid Sonology (JABTS). In the BC-02 study, ultrasound images of 705 DCIS cases were classified by imaging findings. The results showed that non-mass abnormalities accounted for 60% of all lesions and masses for 40%. Looking at each subclassification, hypoechoic areas in the mammary gland were the most common (50% of the total), followed by solid masses (31%), mixed masses (9%), and abnormalities of the ducts (8%)...

Introduction Acute appendicitis is a common surgical emergency. Clinical assessment plays a major role; however, subtle clinical features in early stages and atypical presentation makes diagnosis challenging. Ultrasonography (USG) of the abdomen is a usual investigation that aids in diagnosis, however, it is operator dependent. A contrast-enhanced computed tomography (CECT) of the abdomen is more accurate; however, it exposes the patient to hazardous radiation. The study aimed to combine clinical assessment and USG abdomen in the reliable diagnosis of acute appendicitis...

AIMS AND OBJECTIVES: This study aims to study the variation in the expression of CD117-positive interstitial cells of Cajal-like cells (ICC-LC) across the upper urinary tract region in children presenting with pelvic-ureteric junction obstruction (PUJO) and its association with renal functional and sonological parameters of patients. MATERIALS AND METHODS: A prospective observational study was done on 20 children with congenital PUJO who underwent dismembered pyeloplasty...

OBJECTIVES: To evaluate the diagnostic efficacy of a modified thyroid imaging reporting and data system (TI-RADS) in combination with contrast-enhanced ultrasound (CEUS) for differentiating between benign and malignant thyroid nodules and to assess inter-observer concordance between different observers. METHODS: This study included 3353 patients who underwent thyroid ultrasound (US) and CEUS in ten multi-centers between September 2018 and March 2020. Based on a modified TI-RADS classification using the CEUS enhancement pattern of thyroid lesions, ten radiologists analyzed all US and CEUS examinations independently and assigned a TI-RADS category to each thyroid nodule...

This study compared the diagnostic performance of different ultrasound-based models in discriminating between benign and malignant ovarian masses in a Filipino population. This was a prospective cohort study in women with findings of an ovarian mass on ultrasound. All included patients underwent a physical examination before level III specialist ultrasonographic and Doppler evaluation using the different International Ovarian Tumor Analysis (IOTA) Group's risk models. Serum CA-125 and a second-generation multivariate index assay (MIA2G) were also determined for all patients...

Aim: The aim is to compare the diagnostic accuracy of laboratory investigations and ultrasonography (USG) in distinguishing complicated appendicitis (C-AA) from uncomplicated appendicitis (UC-AA). Materials and Methods: Forty-six children who underwent appendicectomy at our center between November 2018 and July 2020 were included. Based on intraoperative findings, they were divided into two groups - complicated (perforated, gangrenous, or associated with fecal peritonitis; n = 18) and UC-AA ( n = 28)...

Introduction: Post anti-COVID-19 vaccine lymphadenopathies have been recently described in literature, from different parts of the world. Although there have been studies on lymphadenopathy following mRNA vaccines, there is a paucity of studies on lymphadenopathy following inactivated viral vaccines, such as Covishield. Aim: In this study, we explored lymphadenopathy subsequent to Covishield vaccine in terms of its various ultrasound parameters in the Indian population...

OBJECTIVE: A novel agar-based phantom was developed and assessed for ultrasonography (USG)-guided brain biopsy training. The phantom provides visual cues combined with sonologic cues, allowing multimodal training. Impact of multimodal training is evaluated through pretraining and posttraining trials. METHODS: Twenty-five participants were divided based on experience with USG-based procedures into familiar (≥3 procedures performed in the past) (n = 14) and unfamiliar (<3 procedures performed) (n = 11)...

Fatty Liver, one of the most common liver diseases worldwide, usually emerges due to lipid accumulation, mostly triglycerides in hepatocytes. Fat exists in the liver naturally, but if it surpasses 5-10% of the liver's total weight, it can result in fatty liver.

Thirty-five-year-old obese male with grade II fatty liver presented with fatigue, abdominal pain, heaviness, and incomplete bowel evacuation to the National Institute of Ayurveda hospital, Jaipur, Rajasthan, India...

Epidermoid cyst of the spleen is a rare, benign cystic lesion of congenital origin. Although most epidermoid cysts of the spleen are asymptomatic and detected incidentally on ultrasonography, the entity needs to be included in the differential diagnosis of cystic lesion mimics of the spleen, especially in patients with left hypochondriac pain. This case report describes the typical sonological appearance of epidermoid cyst of the spleen in a 31-year-old male.

Testicular torsion is the most common urosurgical emergency in infants, children, and young adolescents, resulting in irreversible ischemic injury within hours; hence demanding urgent surgical attention. It has a bimodal distribution with the highest incidence occurring after puberty, followed by the neonatal period peak. Though the imaging modalities are helpful in the diagnosis, nothing can supersede the clinical findings and judgment.

Ectopic cervical thymus is an essentially benign condition related to embryological development of the thymus and is exceedingly rare among the adult population. Precise and early diagnosis of the entity on high-resolution ultrasonography may help avoid further investigations and unnecessary surgical intervention. This case report describes the typical sonological appearance of ectopic cervical thymus in a 44-year-old male.
