Currently, dissection of the axillary or regional lymph nodes is considered the standard staging procedure in breast cancer. However, accumulating evidence is becoming available that the sentinel node concept may provide the same or even better staging information. In the case of melanoma, it is proven that the histoiogical characteristics of the sentinel node reflect the histological characteristics of the distal part of the lymphatic basin. Morbidity can be reduced significantly by the use of sentinel node dissection as several authors have reported successful introduction of this technique into clinical practice. But in breast cancer patients, there are signigicant differences in practice relating to the technology, such as radiopharmaceuticals, injection sites, volume of injectate, combination with vital blue dye, preoperative lymphoscintigraphy, etc. Valuable reports on these topics appeared in recent journals. This review is a summary of those reports for nuclear physicians interested in sentinel node detection by lymphoscintigraphy in breast cancer patients.

Positron emission tomography (PET) with 2-[F-18]-Fluoro-2-deoxy-D-glucose (FDG) was performed in ninteen patients who had benign musculoskeletal tumors in order to determine if there was a relationship between histologic grade of tumor and FDG uptake of tumor. These patients had been evaluated previously with computed tomography (CT) or magnetic resonance (MR) imaging or both. The diagnoses were confirmed with incisional or excisional biopsy or by radiographic follow-up. Generally high-grade tumors had significantly greater uptake of FDG than low-grade lesions . Benign lesions such as giant cell tumor, fibrous dysplasia, and osteofibrous dysplasia showed significant elevation of SUV (Standardized Uptake Value) above 4.0. On the contrary. The current studies suggest the utility of FDG-PET imaging as an adjunct to CT or MR imaging in the evaluation of benign tumors. And results of PET suggest benign tumors with high SUV are histologically active lesion and tend to be locally aggressive.

Tamoxifen is a nonsteroidal triphenylethylene delivative that has been widely used in the treatment of breast cancer. tamoxifen is indicated for the adjuvant treatment of breast cancer in women following total mastectomy or segmental mastectomy, breast irradiation and chemotherapy. tamoxifen has been shown to have significant benificial effect in the treatment of breast cancer patient as hormonal therapy. However ,there is mounting evidence that tamoxifen may affect other hormon sensitive organs, including the uterus and ovaries. An increased risk of endometrial polyps, endometrial hyperplasia and adenocarcinoma has been reported in tamoxifen treated women. We have met cases of endometrial polyp and endocervical polyp which were associated with tamoxifen use, after modified radical mastectomy for infilterating ductal carcinoma of breast . So we report these cases with the brief review of literatures.

A 55-year-old female experienced acute left shoulder pain without specific trauma. Radiography showed calcific deposits in the inferior part of the glenoid fossa. Magnetic resonance arthrography showed calcific deposits in the origin of the long head of triceps brachii muscle. Conservative treatment failed to resolve the symptoms; therefore, arthroscopic surgery was performed. The patient experienced immediate and dramatic pain relief, and normal shoulder motion was demonstrated 1 year after surgery. In conclusion, although rare, calcific tendinitis of the triceps brachii muscle, which causes shoulder pain, should be included in the differential diagnosis of acute shoulder pain. Arthroscopic surgery is a treatment option for chronic cases and those resistant to conservative treatment.

The accurate diagnosis of spine trauma is essential to its proper management, since therapeutic decisionsdepend on radiography and clinical data. Failure to recognize significant injury to the spine can lead to severeneurological deficit in the previously neulogically intact patient. The developmemt of CT has open a new demensionin evaluation of spinal column. In our experience CT not only offer the accurate and thorough evaluation of spinalinjury, but does so in a rapid and more efficient manner when compared with conventional radiolgraphy. CT hasbecome the diagnostic procedure of choice when screening plain film and clinical examination indecate that acomprehensive radiographic evaluation is necessary. Eighteen patients with thoracic and lumber spinal fracturewere studied with CT. Four had multiple level injuries. The resuls are summerized as follow; 1. Among the 18patients, 4 had multiple level injuries and other 14 patients had single spinal injury. 2. 8 patients (11 spines)had simple compression fracture and 12 patients (13 spines) had burst fracture of vertebral body. 3. 15 spinesamong the 24 involved spines are located at T12 and L1 level. 4. Spineal canal narrowing and bony fragment in thecanal are defiend only 7 of 13 spines (53.8%) of burst fracture in conventional radiography. However CT showed inall spines of burst fracture. 5. Spinal posterior element involvement is suggested only one of 12 spines of burstfracture, but correctly interpretated by CT in 7 spines(11 anatomical position).

Conventional radiology of the pancreas are too often unsatisfactory. It is well known that the whole body CTis very useful in identifying retroperitoneal pathology. The authors intended to present normal pancreaticmorphology and data for preparation of basis for interpretation o abnormalities. We results were as follows; 1.There were 36 male and 24 female patients, and their ages ranged fro 7 to 78 years. 2. 1) The organs adjacentpancreas were stomach, inferior vena cava, duodenum, caudate lobe of the liver left kidney, left adrenal gland,superior mesenteric vessels, spleen. 2) In 19 patients, pancreatic tail at the level of left kidney in thetransverse plane, it was either ventral in 13(68%), ventromedial in 2(19%), ventrolateral in 4(21%) to leftkidney, in the other ventral in 13(68%), ventromedial in 2(19%), ventrolateral in 4(21%) ot left kidney, in theother 41 patients, it was cranial to the upper pole of left kidney, ventral in 15(61%), ventromedial in 1(2%),ventrolateral in 15(37%). 3) Pancreatic tail was cranial to the pancreatic body, 3cm cranial in 2(4%), 2-3cm in5(8%), 1-2cm in 6(10%), less than 1cm in 11(18%). In the other, caudal in 3(5%). 3. Pancreatic shape was uniformtapering form in 37(62%), lobulated form in 23(38%). 4. Pancreatic orientation was horizontal in 13(22%), vertical56(76%), S-shaped in 1(2%). 5. Pancreatic margin was smooth in 22(37%), lobulated in 38(63%). 6. In most patients,pancrease was uniform in density. 7. Pancreatic size was 0.5+-0.1 in measurement ratio of the head in 48(80%),0.4+-0.1 of the body in 49(88%), 0.5+-0.1 of the tail in 47(78%).
