Background: Ultrasound measurements of the liver, gallbladder, and hepatic vessels are important for clinicians as these measurements can be affected anatomically, physiologically, and pathologically. The objective of this study was to determine the correlation between ultrasound measurements and anthropometric measures.

Methods: A prospective observational design was carried in this study. A total of 135 university-aged youth with ages ranging between 18 and 24 years were examined sonographically. Ultrasound measurements include liver length and thickness, gallbladder length, width, thickness, volume and wall thickness, portal and hepatic veins' diameter, and subcutaneous tissue thickness.

Results: A significant and positive correlation was observed between liver length with height (P < 0.001), weight (P = 0.006), body mass index (BMI) (P = 0.025), waist circumference (WC) (P = 0.048), and waist-to-hip circumference ratio (WHR) (P = 0.004). A significant and positive correlation was found between gallbladder volume and portal vein diameter with height (P = 0.034, P < 0.001), weight (P = 0.028, P = 0.032), and BMI (P = 0.047, P = 0.041), respectively. Furthermore, liver length and liver thickness were positively and significantly related with gallbladder volume (P = 0.038, P = 0.047), portal vein diameter (P = 0.029, P = 0.040), and subcutaneous tissue thickness (P = 0.017, P = 0.049), respectively. Gallbladder length and volume were negatively and significantly correlated with gallbladder wall thickness (P = 0.037, P = 0.041, respectively). A significant increase in the liver length, liver thickness, and portal vein diameter was observed in favor of the central obesity group.

Conclusion: Ultrasound measurements confirmed a physiological correlation between liver size with gallbladder volume, portal vein diameter, and subcutaneous tissue thickness. Anthropometric measurements, particularly BMI, are considered determinants for increasing the liver size, gallbladder volume, and portal vein.

Background: The goal of our study is to identify the prevalence of McCleery syndrome and categorize its clinical manifestations in patients who obtained a diagnostic breast ultrasonography at our clinic.

Methods: Five thousand four hundred and twenty cases were reviewed in our clinic for diagnostic breast imaging between May 2021 and May 2022. Five thousand three hundred and two of the cases were female, while 118 were male. Duplex Doppler scanning was used to assess the subclavian vein and the axillary venous structures. The same radiologist performed all examinations; in cases where suspicion was warranted, a second radiologist's opinion was acquired. The diagnosis was confirmed by consensus.

Results: In 52 cases, McCleery syndrome was identified. Between the ages of 36 and 54 years, the average age was 47 years. In four of the patients, magnetic resonance venography supported the diagnosis. In most cases, McCleery syndrome was unilateral. In only two cases was it bilateral. The incidence of McCleery syndrome was 0.95% in our study. Pain was the most often reported symptom (53.8% of 28 cases). No symptoms were reported in 26.9% of the patients.

Conclusion: During a breast ultrasound, radiologists should be aware of McCleery syndrome while assessing the axilla.

Laryngeal cancer is one of the common cancer types, and distant organ metastasis is extremely rare. We present a 65-year-old male patient who received five cycles of cisplatin and radiotherapy after surgery for laryngeal cancer. In the positron emission tomography-computed tomography examination performed during the follow-up, we observed a newly developed mass with increased fluoro-D-glucose uptake in the right breast. A hypoechoic lesion with irregular borders of approximately 17 mm × 11 mm × 17 mm was observed in the retroareolar region of the right breast in ultrasound. Calcification was not observed in mammography. In the pathological evaluation after biopsy, it was seen that the neuroendocrine type of laryngeal cancer was compatible with breast metastasis. Although rare, metastases to the breast should be kept in mind in cases with a primary tumor.

Background: Previous studies have utilized ultrasonography (US) to dynamically evaluate Kager's and infrapatellar fat pads. However, limited research has focused on the dynamic assessment of the posterior fat pad of the elbow joint, and its correlation with elbow pain remains unclear. Therefore, this study aimed to investigate the gliding of the posterior elbow fat pad in healthy patients using US.

Methods: US was performed on 40 healthy patients. The patients were placed in a sitting position with the upper limb on the bed; they performed an automatic movement from 90° flexion to full extension of the elbow joint for 2 s following a fixed rhythm using a digital timer. Moving images of the fat pad gliding were analyzed for the direction of movement and gliding velocity using particle image velocimetry. Statistical analyses were performed using Friedman test.

Results: The posterior fat pad glided into the olecranon fossa within the range of 0%-50% elbow extension. At 50% extension, the posterior fat pad showed a proximal posterior direction of movement. A significant increase in sliding velocity was observed from 0% to 50% extension (P < 0.001). No significant differences were observed between 50% and 75% extensions.

Conclusion: Our results indicate that the velocity and direction of gliding of the fat pad behind the elbow joint in healthy patients vary with changes in the elbow joint extension angle. US proves to be a valuable tool for evaluating the posterior elbow fat pad.

Background: We aim to evaluate thyroid imaging reporting and data system (TIRADS) on the basis of cost and effectiveness through the numbers of fine-needle aspiration biopsies (FNABs) and sonographic examinations in a tertiary health-care institution.

Methods: The 50-day intervals before and after the start of TIRADS use (October 10, 2022) were evaluated to carry out this assessment. The reason for choosing 50-day periods was because it covers the initial phase when the study is most optimally performed in our hospital. The number of thyroid ultrasound (US) and FNAB procedures carried out in our facility during that time was tallied. Exclusion standards were not applied.

Results: One thousand nine hundred eighty-two people made up the study population. Fifty days before the October 10, 2022, there were 975 instances (49.2%), and 50 days after that, there were 1007 cases (50.8%). Out of 1982 cases, it was discovered that 190 (9.6%) underwent a biopsy, and 1792 (90.4%) underwent a US examination. It was found that the first period's rate of biopsy examination was significantly higher than the second period's rates of 11.1% and 8.1%, respectively. The rate of biopsy examination in males during the first period was found to be substantially higher than the second period. Individuals between the ages of 35 and 50 years had a rate of biopsy examination that was considerably higher in the first period than the second period.

Conclusion: The TIRADS Risk Scale has the capacity to reduce unnecessary biopsies, hence mitigating potential psychological distress, burden, and financial expenses for the patient.

Background: Shear wave elastography (SWE) is utilized to detect the stiffness of the coracohumeral ligament (CHL) for the assessment of a frozen shoulder. However, the consistency of shoulder joint posture during the detection process has not been adequately established. This study aims to evaluate the reliability of various commonly employed shoulder postures in measuring CHL stiffness.

Methods: SWE was used to assess CHL stiffness in 55 patients with phase I frozen shoulder by two independent observers. Two measurements were taken, with a 1-week interval, at three shoulder positions: neutral, 30° external rotation, and 60° external rotation. The intra- and inter-observer reliability of CHL stiffness measurements were analyzed using a two-way randomized model with an intragroup correlation coefficient.

Results: Significant differences between intra- and inter-observer measurements of CHL stiffness in the neutral position were observed (P < 0.05). However, no significant differences were found at 30° and 60° of external rotation (P > 0.05). Furthermore, poor intra- and inter-observer reliability of CHL stiffness measurements was established in the neutral position intraclass correlation coefficient (ICC < 0.40), moderate reliability at 30° of external rotation (ICC < 0.40, <.75), and excellent reliability at 60° of external rotation (ICC > 0.75). In addition, the Bland-Altman analyses indicated that the mean differences between intra- and inter-observer measurements of CHL stiffness at 60° of external rotation were closest to the zero scale.

Conclusion: The reliability of SWE in assessing the stiffness of the CHL in patients with phase I frozen shoulder at 60° external rotation is highly satisfactory.
