PURPOSE: To compare qualitative and quantitative magnetic resonance (MR) mammographic features of breast lesions with histopathologic findings, especially tumor angiogenesis. MATERIALS AND METHODS: Seventy-three patients (72 women, one man; aged 30-78 years; mean age, 51.0 years) suspicious underwent MR imaging. Noncontrast medium-enhanced localization imaging then gadolinium-enhanced dynamic fast spoiled gradient-recalled-echo (SPGR) were performed in all patients. In selected patients,...
Thymic carcinomas are rare neoplasms, and information regarding the results of treatment possible prognostic factors in patients with these tumors is limited.The records 40 histologically confirmed thymic carcinoma who were treated between 1984 1998 reviewed. Twenty-seven surgical resection followed by radiotherapy or without chemotherapy, remaining 13 chemotherapy. The median follow-up time for surviving was 87 months (range, 44-193 months).The 5-year 10-year actuarial overall survival...
Optimal management of postoperative radiotherapy for patients with completely resected thymoma remains controversial. This study was conducted to assess the efficacy mediastinal irradiation in thymoma.The records 103 who received during period between 1979 and 1998 were reviewed. The distribution according Masaoka stage Stage I 17 patients, II 61 III 25 patients. Fifty-two treated involved field (IF) irradiation, 51 whole or without boost (WM irradiation). total radiation dose primary tumor...
Computed tomographic (CT) scans of 24 bronchopulmonary sequestrations in 23 patients were reviewed. Seventeen diagnosed at surgery, three angiography, and four on the basis radiographic or CT findings combined with appropriate history. Sixteen intralobar, eight extralobar; 21 posterobasal. occurred left side seven right. Anomalous systemic arterial supply was demonstrated by 16 sequestrations. In others, a artery not shown, presumably because unfavorable orientation small size vessel. The...
To compare lung nodule detection performance (LNDP) in computed tomography (CT) with adaptive iterative dose reduction using three dimensional processing (AIDR3D) between ultra-low CT (ULDCT) and low (LDCT).This was part of the Area-detector Computed Tomography for Investigation Thoracic Diseases (ACTIve) Study, a multicenter research project being conducted Japan. Institutional Review Board approved this study informed consent obtained. Eighty-three subjects (body mass index, 23.3 ± 3.2)...
Abstract BACKGROUND Brain metastases from esophageal carcinoma are extremely rare, and information regarding the natural history, results of treatment, possible prognostic factors in these patients is limited. METHODS The records 36 with brain who were treated between 1986 2000 reviewed. For metastases, 12 (33%) surgical resection followed by radiation therapy (S+RT), remaining 24 alone. RESULTS At initial diagnosis carcinoma, median primary tumor length was 8 cm (range, 2–19 cm), 26 32...
Abstract Purpose: Human kallikrein gene 6 (KLK6) is a member of the human family, and recent studies have found that many kallikreins altered expression patterns in various malignancies. The purpose current study was to quantify KLK6 malignant benign colorectal tissues statistically analyze whether levels correlate with clinicopathologic variables prognosis patients cancer. Experimental Designs: Paired tissue samples from cancerous corresponding noncancerous were obtained 63 cancer who...
Purpose: To analyze margin characteristics of pulmonary nodules on highresolution CT (HRCT) in order to improve imaging diagnoses. Material and Methods: HRCT images 193 less than 30 mm maximum diameter (113 primary cancers, 15 metastatic 55 inflammatory nodules, 10 benign tumors) were reviewed classified as 6 types margins: round, lobulated, densely spiculated, ragged, tentacle or polygonal halo. the relationships these diagnoses, underlying pathological features, mainly those tumor growth...
We sought to assess the CT features of surgically resected large cell neuroendocrine carcinoma lung.The cases all patients who underwent surgical resection for primary lung cancer in a single institution from 1993 2000 and received an initial diagnosis poorly differentiated non-small carcinoma, small carcinoid tumor, were histologically reviewed. The findings 43 reclassified confirmed as carcinoma. scans available 38 evaluated by two observers.In patients, six central tumors 32 peripheral...
Abstract BACKGROUND The relative roles of surgical resection, radiotherapy, and chemotherapy in the management patients with intracranial nongerminomatous malignant germ cell tumors have been controversial. authors retrospectively investigated results different treatment regimens these tumors. METHODS records 41 who were treated between 1981 2001 reviewed. They grouped into a good prognosis ( n = 3), an intermediate 24), poor 14) based on histology their Fifteen (37%) underwent resection...
Purpose: Our goal was to assess the utility of breathing dynamic cine MR (BDCMR) in evaluation tumor invasion chest wall bronchogenic carcinomas. Method: BDCMR imaging performed preoperatively 25 patients with carcinomas adjacent wall. Twelve sequential images were obtained same coronal and/or sagittal planes during one respiratory cycle fast spoiled GRASS sequence, and analysis cine-loop display performed. Results: In all 14 cases which free movement along parietal pleura on demonstrated,...
Bronchial artery embolization (BAE) is a well-accepted and widely used treatment modality for the management of massive recurrent hemoptysis. However, few reports have previously investigated long-term results.To investigate prognosis patients with hemoptysis who had undergone BAE.Twenty-two underwent BAE. The underlying diseases included bronchiectasis in 9, aspergillosis 3, chronic bronchitis 2, idiopathic bronchial bleeding 4, other 4. follow-up period ranged from 25 to 88 months (median...
Our goal was to review patterns of peripheral enhancement on contrast-enhanced MRI the breast and correlate radiologic findings with pathologic features.We reviewed MR images 124 consecutive women lesions. Peripheral identified in 35 (32 malignant, 3 benign) were correlated features including microvessel density distribution determined histologically.Early centripetal progression seen invasive carcinomas a high low central density, associated fibrosis and/or necrosis (n = 18; 15 fibrosis, 2...
