Three-dimensional ultrasound-guided breast interventionCho KS, Moon WK, Chen D-R, Chang R-F, Cha JH, Im J-G,Healthcare System Gangnam Center, Seoul National UniversityHospital, Korea; Seoul National University Hospital, Korea, ChinaMedical College and hospital, Taiwan; National Chung ChengUniversity, Taiwan; Seoul National University Boramae Hospital,Korea

Ultrasound (US) is indispensable for guiding breast interventionalprocedures including cyst aspiration, core needle biopsy, preoperativeneedle localization and minimally invasive therapy (percutaneous tu-mor excision and tumor ablation). Three-dimensional (3D) US canfurther improved these procedures with its multiplanar display capa-bilities and computer-aided volume calculation. Four-dimensional (4D)US is dynamic real-time 3D US with a continuous volume data acqui-sition and rendering process. 4D US can be useful for improving thedepiction and understanding of the geometric relationships of biopsyneedles to target lesions and guiding the biopsy procedures success-fully. 3D US can offer the advantage of better preoperative demonstra-tion of the lesions’ margins, resulting in better assessment of volum-etry, and perioperative identification of residual tumor tissue. Storedimage volume by 3D US also offers advantages in terms of imagedocumentation for interventional radiologists.

Imaging analysis of inflammatory breast lesions focusing onsonographic findingsAn JK, Choi YS, Woo JJ, Kim HS, Kim SH, Park SW, Han CY, EuljiHospital, Eulji University, School of Medicine, Korea

Inflammatory breast lesions are clinically common disease. Womenbetween the ages of 18 and 50 years are commonly affected and it canbe lactational or nonlactational. Pain, palpable lesion, warmth anderythematous skin change are common symptom and physical findingsto be diagnostic. Imaging provides important information about loca-tion, extent, abscess formation and guiding of interventional procedure.Sonography is especially useful to evaluate the conditions as the firstchoice of imaging study. It is important for radiologist to be familiarwith these conditions. This exhibition illustrates various sonographicfindings of inflammatory breast lesions, including puerperal mastitis,granulomatous lobular mastitis, tuberculosis, sparganosis infection,nipple and subareolar abscess and hyperprolactinemia related chronicinflammation.

The spectrum of imaging findings of the systemic diseasesinvolving breastLee JY, Kim MJ, Youk JH, Kim EK, Oh KK, Yousei UniversityCollege of Medicine, Korea

Systemic diseases infrequently involve the breast. Some disorders havea characteristic imaging features but others may mimic breast cancer.The familiarity with the imaging findings and consideration of systemiccauses in the differential diagnosis may help the management ofpatients. The imaging findings through mammography and ultrasonog-raphy of breast lesions caused by systemic diseases including collagenvascular disease, diabetes mellitus, congestive heart failure, endocrinediseases, hematologic disease and granulomatous diseases were de-scribed and discussed.

How to expand the FOV in breast ultrasoundLee SH, Moon WK, Cho N, Cha JH, Seoul National UniversityHospital, Korea; Boramae Hospital, Korea

Several approaches have been developed to obtain a larger FOV inbreast US. First, the length of the transducers can be increased. A50-mm long high-frequency linear transducer is commercially avail-able. Second, a lower-frequency curved transducer can be used. This iseffective for demonstrating the shape of the implant and a mass withgreat AP dimension. Third way is to phase the beam and to create atrapezoidal image. Fourth approach is extended FOV technology. Itfacilitates panoramic images with no loss in resolution by manualmovement of a probe in the direction of the transducer array. Final wayis to use split-screen imaging and combining the both images into asingle fused image. Larger FOV image improves the visualization anddocumentation of large and multiple lesions, thus allowing betterassessment of traditional criteria, measurement and comparison of thelesions during follow-up or treatment and improves preoperative deci-sion making.

Analysis of tissue motion vector estimate utilizing syntheticaperture array signal processing coupled with virtual sourcegenerationNishiyama T, Yagi S, Meisei University, Japan

Objectives: As an approach to real-time quantitative elastography, theadvanced measurement system of tissue local motion vector withhigh-speed and excellent accuracy was numerically analyzed.Methods: As for the estimation accuracy of this measurement methodwith synthetic-aperture array signal processing that uses the transmitwave from virtual source generation, the evaluate value is analyzed bythe simulation.Results: In the simulation, displacement in 0.05 mm was given to thelongitudinal displacement or the lateral displacement in target area. Asa result, the evaluation of local motion vector was estimated with 2%in the longitudinal displacement and 10% in the lateral-displacement.Conclusions: The combination of cross correlation motion estimateand synthetic aperture processing with ultrasonic virtual source gener-ation is a promising tool for the evaluation of local motion vectoracross a living tissue in both accuracy and speed.

Ultrasonographic guided mammotome excisional biopsy forabdominal wall masses: A case reportPark NH, Lee EJ, Kim MS, Park SI, Ryu JA, Park CS, MyongjiHosp, Kwandong University, College of Medicine, Korea

Objectives: To introduce the usefulness of mammotome excisionalbiopsy for the soft tissue mass other than breast mass.Methods: A 37-year old man who had underwent oriental acupunc-tures on the abdominal wall 4 years ago, presented three painfulpalpable masses on previous acupuncture sites since 3 months ago. Thelargest one measuring as about 1.5 cm in diameter at the suprapubicarea was surgically excised but recurrent abscess and seroma weredeveloped at operation site. The two smaller masses measuring about0.38 � 0.25 cm and 0.38 � 0.31 cm, respectively, were requested formammotome excision (Biopsy Medical/Johnson and Johnson, Cincin-nati, OH) under ultrasound (ATL(Advanced Technology Laboratories),Bothell, WA, HDI 5000) guidance.Results: Two painful small palpable lesions were successfully excisedby mammotome with an 11 gauge probe under ultrasound guidance.
