MRI findings in 28 cases of various types of mediastinal mass diagnostically confirmed by pathological studies were reported. The value of MRI in the diagnosis of mediastinal mass was evaluated. The main advantage of MRI was high accuracy in estimating the spatial dimension. All of 28 cases were located accurately.

It can be show different characteristics in the MRI of the orbital diseases, the sheath of the orbital tumor contain certain characteristics, can express soft muscle locate the orbital compartment or outside. and the tumor showed hypointensity or hypo-or isointense mass on T1-weighted images, and iso-or hyperintense or hyperintense mass on T2-weiglited images, inflammation expresses for the orbital inside limit the soft muscle or widespreads excrescent signal, and showed hypo-or isointense mass on Ti-weighted images, and iso-or hyperintense mass on T2-weighted images, the companion contain fatty the eye muscle big or the eye wreath increase thick, the lachrymal gland is swollen.

其在MRI表现各具有影像学特征，眼眶肿瘤多表现为位于眼眶内、外的局限性软组织肿块，MR T1WI呈等或稍低信号，T2WI呈高或等信号多见；炎性假瘤则表现为眶内局限性软组织肿块或弥漫性异常信号，MR T1WI呈低信号，T2WI呈高信号，常伴有眼肌肥大或眼环增厚，泪腺肿大等。

ResultsThirty-one cases of intramural myoma with hysterauxesis;2 cases of submucous myoma with orbicular-ovate space-occupying mass in cavitary uteri;4 cases of subserous myoma withh CT features of clear and lobulated mass or round mass at the edge of the uterus.ConclusionCT shows the location,size of hysteromyom,and the relationship with the uterus clearly,can also provides a clinical diagnosis to doctors.

结果：壁间肌瘤31例，主要表现为子宫增大；黏膜下子宫肌瘤2例，表现为宫腔内卵圆形占位性肿块；浆膜下肌瘤4例，主要征象是子宫肿块呈明显分叶状或子宫边缘的圆形肿块；结论：CT对子宫肌瘤的位置、大小以及与子宫的关系显示比较明确，给临床医生提供重要的诊断依据。

The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.

骨肉瘤基本影像表现为骨质破坏、骨膜反应、瘤骨和软组织肿块。49例X线表现为成骨型19例，溶骨型13例，混合型17例；X线对骨质破坏、骨膜反应、软组织肿块、瘤骨和Codman三角的检出率分别为61.2%、95.9%、71.4%、73.5%和27.7%；10例CT表现均可见骨质破坏、软组织肿块及瘤骨，CT对骨膜反应、筛孔征和Codman三角的检出率为90%、90%和11%；CT对显示细小肿瘤骨和筛孔征最敏感，但对Codman三角的显示不如X线平片；32例MRI表现为骨髓腔内正常的骨髓高信号被肿瘤信号所取代，T1WI呈低～等信号，T2WI呈混杂信号，7例合并出血，24例中央坏死囊变，32例增强扫描均呈不均匀强化及瘤周可见水肿区。

CT images of SMA5 frequently show lobulate lesions with strongly enhanced solid and cystic components. UA occurs mostly in young patients, and typically appears as cystic lesion with mild to moderate enhancement of the wall on CT images. MA often appears in old patients, and shows extensive bone destruction, soft tissue mass, ill-defined margin, and strong enhancement on CT images.

SMA多见于中年人，在CT上多表现为强化明显的囊实性肿块，边界清楚；UA常见于年轻人，在CT上表现为囊性肿物，囊壁轻中度强化；MA多见于老年患者，在CT上常显示广泛骨破坏，软组织肿块常见，强化明显，边界不清。

The mass was closely related to the tuber cinereum or the mammillary body and appeared isodense to cortex but not enhanced on CT scans.

肿块与灰结节或乳头体相连，CT表现为与皮质等密度的不增强肿块。

Results: Most synovial sarcomas located in the extremities close to joints. Synovial sarcomas detected by radiography typically appeared as round, oval or multilobulated juxtaarticular soft-tissue masses with calcification in some cases. The most common CT appearance of synovial sarcoma was heterogeneous deep -seated soft-tissue mass with attenuation similar to or slightly lower than that of muscle. On T1WI, synovial sarcomas typically appeared as prominently heterogeneous multilobulated soft tissue masses with signal intensity similar to or slightly higher than that of muscle. On T2WI, synovial sarcomas appeared as prominent heterogeneity with predominantly high signal intensity.

结果：大部分滑膜肉瘤位于关节旁；X线表现为圆形、椭圆形或分叶状软组织肿块，部分可见肿块内钙化；典型的CT表现为较深在的、等或稍低密度不均匀的软组织肿块；磁共振T1WI与肌肉信号相比，滑膜肉瘤表现为分叶状、不均匀、等或稍高信号，T2WI则表现为高信号为主的不均匀信号；DSA呈显著的肿瘤实体染色及新生血管。

Results CT scan indicated that cancer relapsed 3 to 84 months after surgery.For patients with colostomy,the CT scan showed nodular or lobulated mass in the areas of perineum and presacralis,as well as loss of presacral fat space.For patients without colostomy.CT finding included thickened rectal wall with unregular proximal tumor,rectal obliteration,rectostenosis and ddisplacement of perirectal fat space.

结果 肿瘤复发的CT表现：造瘘术后CT表现为会阴及骶前区肿块，呈结节状或分叶状，骶前脂肪间隙消失；无造瘘术后CT表现新直肠壁增厚伴不规则偏心性肿块，管腔狭窄及闭塞，直肠周围脂肪间隙狭窄移位。
