What nodule features increase TI-RADS score?

What is a Nabothian cyst?

During a first-trimester ultrasound for nuchal translucency (NT) screening at 12 weeks gestational age, the sonographer obtains a measurement of 3.2 mm. What is the clinical significance of this finding?

A 36-week gestation fetus is undergoing a biophysical profile (BPP). The sonographer observes 3 episodes of fetal breathing movements lasting at least 30 seconds each, 4 movements of the fetal trunk/limbs, and good fetal tone. The amniotic fluid index (AFI) is 12 cm. What is the BPP score, and what does it indicate?

What is the normal cardiothoracic ratio (CTR) in the fetus?

During a breast ultrasound for a palpable lump, a 1.0 cm hypoechoic, irregular mass with spiculated margins and posterior shadowing is identified at the 12 o'clock position in the right breast. What is the most appropriate next step based on this sonographic finding?

A 68-year-old male presents for a carotid duplex ultrasound due to a recent TIA. The ICA/CCA ratio is calculated as 3.5, and the ICA peak systolic velocity (PSV) is 180 cm/s. The contralateral CCA PSV is 80 cm/s. Based on these findings, what is the most likely degree of ICA stenosis according to standard criteria?

What is the normal Achilles tendon thickness?

A 42-year-old male presents with blunt abdominal trauma after a motor vehicle accident. An eFAST exam is performed. Which specific view within the eFAST protocol is most likely to detect a splenic laceration with associated hemoperitoneum?

During a carotid duplex ultrasound, the sonographer identifies a high-grade stenosis in the internal carotid artery. To obtain a more accurate Doppler shift and velocity measurement, the sonographer should primarily adjust which of the following parameters?
