“…자기공명영상에서만 확인되는 병변이므로 수술 직후 표본촬영술을 통해 병변이 포함되었는지 여부를 확인할 수 없어 최종 병리 결과를 꼭 확인해야 한다. 자기공명영상 유도하 침위치결정술은 안전하고 정확도가 높은 시술로 알려져 있으나, 장비가 갖춰진 시설에서도 시술에 대한 경험이 부족해 흔히 이루어지는 시술은 아니다( 42 ).…”

국내에 자기공명영상의 보급의 증가와 함께 유방 자기공명영상의 건수도 지속적으로 증가하고 있다. 하지만 이에 비해 자기공명영상 유도하 조직생검술 및 침위치결정술과 같은 유방의 중재적 시술은 초음파 유도하 시술이나 입체정위생검술에 비해 많이 이루어지지 않는다. 유방 자기공명영상은 다른 유방 영상 검사들에 비해 높은 민감도를 보이는 검사법이지만 그 특이도는 제한되는 검사법이기 때문에, 자기공명영상에서만 발견된 병변들은 자기공명영상 유도하 조직생검술이나 자기공명영상 유도하 침위치결정술을 통한 수술적 절제를 통하여 병리적 진단이 이루어져야 한다. 이러한 배경을 바탕으로, 본 종설에서는 자기공명영상 유도하 유방의 중재적 시술들의 적응증, 시술 방법, 시술 과정에서의 여러 고려 사항 및 제한점들에 대해 다루고자 한다.

“…When the coordinates of the target have been identified through computer software which is in the previous description, the skin entry site and optimal needle trajectory would be selected, and the needle guide and the needle are introduced through the grid hole overlying the skin [56]. In the method of freehand technique, the needle trajectory should base on the desired surgical approach, and a full range of angled paths within the axial plane can be available as far as possible.…”

“…The localization of superficial target lesions is often performed using a particular marker, such as vitamin E, over the skin because there is not enough tissue depth to adequately secure a localization wire in place [24]. For lesion close to the nipple, where the nipple may be difficult to stabilize, the needle may be placed adjacent to the lesion instead of through the lesion [56].…”

With a high sensitivity of breast lesions, MRI can detect suspicious lesions which are occult in traditional breast examination equipment. However, the lower and variable specificity of MRI makes the MRI-guided intervention, including biopsies and localizations, necessary before surgery, especially for patients who need the treatment of breast-conserving surgery (BCS). MRI techniques and patient preparation should be first carefully considered before the intervention to avoid lengthening the procedure time and compromising targeting accuracy. Doctors and radiologists need to reconfirm the target of the lesion and be very familiar with the process approach and equipment techniques involving the computer-aided diagnosis (CAD) tools and the biopsy system and follow a correct way. The basic steps of MRI-guided biopsy and localization are nearly the same regardless of the vendor or platform, and this article systematically introduces detailed methods and techniques of MRI-guided intervention. The two interventions both face different challenging situations during procedures with solutions given in the article. Post-operative statistics show that the complications of MRI-guided intervention are infrequent and mild, and MRI-guided biopsy provides the pathological information for the subsequent surgical decisions and MRI-guided localization fully prepared for follow-up surgical biopsy. New techniques for MRI-guided intervention are also elaborated in the article, which leads to future development. In a word, MRI-guided intervention is a safe, accurate, and effective technique with a low complication rate and successful MRI-guided intervention is truly teamwork with efforts from patients to surgeons, radiologists, MRI technologists, and nurses.

“…To address the challenge, real-time feedback is highly required. Usually, medical imaging devices are used, such as ultrasound (US) [9], computerized tomography (CT) [10,11], or magnetic resonance imaging (MRI) [2,12]. Generally, the image-guided percutaneous interventions are conducted with the use of CT or MRI.…”

Flexible needles have been widely used in minimally invasive surgeries, especially in percutaneous interventions. Among the interventions, tip position of the curved needle is very important, since it directly affects the success of the surgeries. In this paper, we present a method to estimate the tip position of a long-curved needle by using 2D transverse ultrasound images from a robotic ultrasound system. Ultrasound is first used to detect the cross section of long-flexible needle. A new imaging approach is proposed based on the selection of numbers of pixels with a higher gray level, which can directly remove the lower gray level to highlight the needle. After that, the needle shape tracking method is proposed by combining the image processing with the Kalman filter by using 3D needle positions, which develop a robust needle tracking procedure from 1 mm to 8 mm scan intervals. Shape reconstruction is then achieved using the curve fitting method. Finally, the needle tip position is estimated based on the curve fitting result. Experimental results showed that the estimation error of tip position is less than 1 mm within 4 mm scan intervals. The advantage of the proposed method is that the shape and tip position can be estimated through scanning the needle’s cross sections at intervals along the direction of needle insertion without detecting the tip.
