4 syllables: hy, per, echo, ic. Stress on echo.
heye-pur-EK-oh-ik
/ˌhaɪpɚˈɛkoʊɪk/
hyperechoic is pronounced heye-pur-EK-oh-ik (/ˌhaɪpɚˈɛkoʊɪk/). It has four syllables (hy-per-echo-ic), with the stress on "echo". Hyperechoic describes a tissue that reflects more ultrasound waves than surrounding tissues, appearing unusually bright on an ultrasound image. It conveys a high echogenicity compared with reference structures and is used primarily in medical radiology and sonography to characterize tissues or lesions. The term combines 'hyper-' (excessive) with 'echoic' (reflective).

"The lesion appeared hyperechoic on the Doppler ultrasound, suggesting a dense composition."
"Radiologists noted hyperechoic foci within the liver lesion during the scan."
"Certain calcifications are hyperechoic relative to surrounding soft tissue, aiding diagnosis."
Hyperechoic is pronounced hi-puh-ECKH-ik, with primary stress on the third syllable (ˌhaɪ.pəˈiː.kɒɪk). Break it into hi- (as in high), -pe- (as in per), echo- (EH-koh), and -ic (ik). For clarity, say /ˌhaɪ.pəˈiː.kɒɪk/ in US, /ˌhaɪ.pəˈiː.kəʊɪk/ in UK, and /ˌhaɪ.pəˈiː.kɒɪk/ in Australian. Use a crisp, definitive closing consonant on the -ic ending to avoid trailing vowel sounds. Audio reference: imagine saying “high puh EEK-ik” quickly but with correct syllable boundaries. IPA guidance helps ensure you’re not merging 'echo' with 'ek.'
Two frequent errors are flattening the schwa in the second syllable and misplacing the stress, often saying he-PER-echo-ik or hi-pere-ECH-ik. Correct by stressing the /ˈiː/ in the third syllable: hi-puh-EE-koh-ik, ensuring /ˈiː/ is held slightly longer and that the /k/ at the end is crisp. Another pitfall is merging 'echo' into a single smooth syllable; instead, articulate the /ˈiː.kɒɪ/ sequence as two distinct parts. Practice with slow, measured syllables before speed.
In US and UK, the primary stress remains on the third syllable, but vowel quality shifts: US tends to a longer /iː/ and a more rounded /ɒɪ/ in -echo-; UK often features a slightly tighter /ɒɪ/ diphthong and clearer /ˈiː/ in the middle. Australian tends toward broader diphthongs and a more evident /ɪ/ in the second syllable; final -ic remains /ɒɪk/ or /aɪk/ depending on speaker. Overall, the rhythm is similar, but vowel qualities and rhoticity influence the exact vowel shapes. IPA references: US /ˌhaɪ.pəˈiː.kɒɪk/, UK /ˌhaɪ.pəˈiː.kəʊɪk/, AU /ˌhaɪ.pəˈiː.kɒɪk/.
The difficulty comes from the long, multi-syllabic sequence with a late stress and the /ɒɪ/ diphthong in the final half, which can blur into /ɒɪk/ or /aɪk/ for non-native speakers. The /pə/ mid syllable weakens, making it easy to reduce to /pə/ or truncate the /iːk/ cluster. Sound placement requires precise lip rounding and tongue elevation for /ɪː/ and /ɒɪ/. Focus on clear separation of the three open syllables and the final hard /k/.
There are no silent letters in hyperechoic; every letter contributes to the syllable structure. A unique focus is the three-part structure: hi- (start with a light alveolar /h/ plus /aɪ/), -pe- (unstressed /pə/), and -echoic (echoic with a clear /iː.kɒɪk/). The key is ensuring the /p/ is released cleanly and the /ˈiː/ is held, while the final /k/ lands crisply. There is no silent letter, but the middle syllable often carries reduced vowel, which can cause mispronunciation if you overemphasize it.

Hyperechoic is built from the combining form hyper- (Greek hyper, meaning over, beyond, excessive) and echoic (from echo, from Greek ēkhō, to sound or resound, with the suffix -ic forming adjectives). The medical term emerged with the rise of diagnostic ultrasound in the 20th century, where the brightness of tissues on an image directly reflects their acoustic impedance. Early radiology literature described terms like hyperechoic and hypoechoic to differentiate tissue interfaces by echogenicity. The first known uses appear in radiology reports and medical dictionaries of the 1960s–1980s as ultrasound technology matured, with hyperechoic becoming standard vocabulary for bright, dense, reflective structures seen on ultrasound scans. In practice, hyperechoic denotes higher-than-normal reflectivity, often due to calcifications, fat, fibrosis, or dense tissues, and it is commonly paired with keywords like lesion or foci in radiologic descriptions.
