Midterm results of radiofrequency ablation versus nephrectomy for T1a renal cell carcinoma
Radiation Medicine - Tập 28 - Trang 460-468 - 2010
Haruyuki Takaki, Koichiro Yamakado, Norihito Soga, Kiminobu Arima, Atsuhiro Nakatsuka, Masataka Kashima, Junji Uraki, Tomomi Yamada, Kan Takeda, Yoshiki Sugimura
The aim of this study was to retrospectively evaluate midterm results of renal radiofrequency (RF) ablation compared to the results after nephrectomy in patients with T1a renal cell carcinoma (RCC). A total of 115 patients with a single RCC measuring ≤4 cm (T1a) were included; 51 patients underwent RF ablation, 54 patients radical nephrectomy, and 10 patients partial nephrectomy. The survival and ...... hiện toàn bộ
Primary cardiac lymphoma: computed tomography and magnetic resonance imaging features
Radiation Medicine - Tập 27 - Trang 243-246 - 2009
Daisuke Utsunomiya, Kazuo Awai, Joji Urata, Touitsu Hirayama, Yasuyuki Yamashita
Primary cardiac lymphoma is a rare, extremely aggressive malignancy. Early diagnosis and treatment is important for patient survival. We present a case of a 76-year-old woman admitted for worsening dyspnea caused by a large tumor in the right atrium. Magnetic resonance imaging and computed tomography clearly depicted the primary cardiac tumor, and histopathological study of the surgical specimen c...... hiện toàn bộ
MR imaging of thymic epithelial tumors: correlation with World Health Organization classification
Radiation Medicine - Tập 24 - Trang 171-181 - 2006
Atsuo Inoue, Noriyuki Tomiyama, Kiminori Fujimoto, Junko Sadohara, Itsuko Nakamichi, Yasuhiko Tomita, Katsuyuki Aozasa, Mitsuko Tsubamoto, Sachiko Murai, Javzandulam Natsag, Hiromitsu Sumikawa, Naoki Mihara, Osamu Honda, Seiki Hamada, Takeshi Johkoh, Hironobu Nakamura
The aim of this study was to determine magnetic resonance imaging (MRI) features of various subtypes of thymic epithelial tumors based on the World Health Organization classification. The study included 64 patients with histologically proven thymic epithelial tumors. Two observers evaluated the MRI findings in terms of tumor size, contour, lobulation, shape, homogeneity, the presence of intratumor...... hiện toàn bộ
Radiation therapy after breast-conserving surgery
Radiation Medicine - Tập 24 - Trang 388-404 - 2006
Naoyuki Shigematsu, Atsuya Takeda, Naoko Sanuki, Junichi Fukada, Takashi Uno, Hisao Ito, Osamu Kawaguchi, Etsuo Kunieda, Atsushi Kubo
The authors critically reviewed previous articles concerning the significance of breast irradiation following breast-conserving surgery in terms of the following subject items: indications for breast-conserving therapy, the significance and complications of breast irradiation, the timing of the start of breast irradiation, the significance of boost irradiation, the potential improvement of surviva...... hiện toàn bộ
Mucoepidermoid carcinoma of an adolescent epiglottis
Radiation Medicine - Tập 28 - Trang 692-694 - 2010
Hiroko Tanaka, Atsushi Kohno, Kazuyoshi Kawabata, Yukiko Sato
Laryngeal mucoepidermoid carcinoma is rare and extremely rare in adolescents. We present the case of a 17-year-old girl. Magnetic resonance imaging clearly depicted the tumor, and histopathological study of the surgical specimen confirmed the diagnosis of mucoepidermoid carcinoma.
Spontaneous internal oblique hematoma successfully treated by transcatheter arterial embolization
Radiation Medicine - Tập 26 Số 7 - Trang 446-449 - 2008
T. Nakayama, Tatsuyuki Ishibashi, Daihiko Eguchi, Kinya Yamada, Daisuke Tsurumaru, Katsumi Sakamoto, Hiromu Hidaka, Hiroto Masuda
Intense accumulation of gallium-67 citrate in pancreatic endocrine tumor
Radiation Medicine - Tập 24 Số 6 - Trang 456-458 - 2006
Rieko Watanabe, Harunao Iizuka, Kyoichi Kaira, Takanori Mori, Atsushi Takise, Jun Ito, Atsushi Motegi, Yoshikuni Onozato, Hiroshi Ishiguro
Spontaneous splenic rupture due to extensive venous malformation with consumptive coagulopathy: treatment with splenic artery embolization
Radiation Medicine - Tập 28 - Trang 381-384 - 2010
Ho Jong Chun, Keigo Osuga, Isao Ukai, Masataka Ikeda, Tomio Kawasaki, Hironobu Nakamura
Extensive venous malformation (VM) is often associated with chronic consumptive coagulopathy, which may result in bleeding complications. We report herein the case of a 25-year-old man with extensive VM involving the left lower extremity who presented with hypovolemic shock and abdominal distension without abdominal trauma. Abdomen computed tomography revealed splenic rupture with massive hemoperi...... hiện toàn bộ
Change in dose distribution of three-dimensional conformal radiotherapy during treatment for lung tumor
Radiation Medicine - Tập 24 - Trang 122-127 - 2006
Kazunari Yamada, Keisuke Iwai, Ryu Kawamorita, Yoshishige Okuno, Toshifumi Nakajima
We investigated the changes in dose distribution of three-dimensional conformal radiotherapy (3D CRT) during lung tumor treatment. Ten patients with non-small cell lung cancer who had undergone planning for radical radiotherapy were selected for study. Computed tomography (CT) examination was performed at two time intervals during the course of conformal radiotherapy: t0 Gy at the time of planning...... hiện toàn bộ
Metastasis of humeral osteosarcoma to the contralateral breast detected by 99mTc-MDP skeletal scintigraphy
Radiation Medicine - Tập 27 - Trang 455-457 - 2009
Sandip Basu, Surendra H. Moghe, Tanuja Shet
A rare case of osteogenic sarcoma (OGS) of the left humerus metastasizing to the right breast is presented. This lesion was detected by serendipitous observation on 99mTc-MDP skeletal scintigraphy that demonstrated a rounded focus just outside the skeletal outline of the right chest. The focus remained at a similar location on repeat postwash view. Clinical examination revealed a breast mass corre...... hiện toàn bộ
