Objective: To investigate the relationship between the pathological types of lung cancer and the number of intracranial hemorrhagic metastases. Methods: The clinical imaging findings of 43 cases of intracranial hemorrhagic metastases from lung cancer confirmed by pathology were retrospectively analyzed, and the correlation between imaging features of intracranial hemorrhagic metastases from lung cancer and the pathological types of the primary tumor were evaluated. Results: All 43 cases of intracranial hemorrhagic metastases showed hematoma, and 29 cases of them showed hemorrhage within or around tumor, 20 cases of tumor edge were not very clear, 9 cases of tumor signal range is larger, enhanced MRI showed a ring or patchy enhancement. In addition, there was no obvious enhancement in 14 cases. The intracranial hemorrhagic metastases from adenocarcinoma (20 cases of multiple lesions, 4 cases of single lesion), from small cell carcinoma 14 cases(3 cases of multiple lesions, 11 cases of single lesion), from squamous cell carcinoma 4 cases(1 case of multiple lesions, 3 cases of single lesion), and from large cell neuroendocrine carcinoma 1 case (single lesion). Statistically, the ratio of adenocarcinoma and small cell carcinoma with hemorrhagic brain metastasis was significantly higher than that of squamous cell carcinoma and Large cell neuroendocrine carcinoma, and there was no significant difference between adenocarcinoma and small cell carcinoma. 5 cases of all patients were misdiagnosed. Conclusion: The MR imaging findings of intracranial hemorrhagic metastases from lung cancer have certain features, and enhanced MRI is helpful for qualitative diagnosis of brain metastasis. The intracranial hemorrhagic metastases from lung cancer was correlated with pathological types of the primary tumor. Adenocarcinoma and small cell carcinoma complicated with hemorrhage more common, squamous cell carcinoma and large cell carcinoma is relatively less.

DOI:
Objective: To investigate the classification and definition of intracranial metastasis associating with cerebral cortex by double-dose Gadobutrol and delayed contrast-enhancement of MR scanning using 3D MPRAGE sequences. Methods: Twenty-five patients with suspected intracranial metastases were retrospectively analyzed. All patients underwent MRI examination, which included T1WI, T2WI, FLAIR and delayed contrast-enhancement of MR scanning using 3D MPRAGE sequences.The intracranial metastases were classified and defined according to the images of 3D-MPRAGE. The metastasis, located in the cerebral cortex, at the edge of the cerebral cortex and at the corticomedullary junction, was taken as TypeⅠ, TypeⅡ, Type Ⅲ, respectively. Results: 121 metastatic lesions(6 in typeⅠ, 10 in type Ⅱ, 105 in type Ⅲ) associating with cerebral cortex were found using 3D MPRAGE sequences. Type Ⅲ account for 95.7% of 121 metastatic lesions. There was a positive correlation between the tumor size and tumor typing(rs=0.441, P<0.05). Conclusion: Delayed and double-dose Gadobutrol contrast-enhancement of MR scanning using 3D MPRAGE sequences can clearly display the relationship between intracranial metastasis and cerebral cortex. The intracranial metastasis associating with cerebral cortex were divided into three types and most intracranial metastasis are seen at the corticomedullary junction.

AN He;SHI Yu;GUO Qi-yong
DOI:
Objective: To evaluate the feasibility of using 3D magnetic resonance elastography(3D MRE) to assess the pancreatic stiffness in healthy volunteers. Methods: Twenty-one volunteers without pancreatic-related diseases underwent GE 3.0T MR exams using a multi-slice EPI pulse sequence with low-frequency vibrations(40 and 60 Hz). The mean stiffness in three pancreatic subregions(head, body and tail) and the corresponding liver stiffness were calculated. Results: The mean stiffness(average of values obtained in different pancreatic subregions) was (1.11±0.16) kPa at 40 Hz, and (2.08±0.31) kPa at 60 Hz. The corresponding liver stiffness was (1.62±0.26) kPa at 40 Hz(mean pancreas-to-liver stiffness ratio: 0.69), and (2.27±0.34) kPa at 60 Hz(mean ratio: 0.92). The mean stiffness in three pancreatic subregions have no significant differences(P>0.05). The mean CV for each pancreatic subregion was lower at 40 Hz than 60 Hz(P<0.05 for all subregions, range: 13.91%~20.91% at 40 Hz and 18.84%~21.84% at 60 Hz). Conclusion: 3D MRE can provide pancreas stiffness measurements in healthy people, with lower variation at 40 Hz. There was no difference of stiffness among different pancreatic subregions.

ZHANG Lian-na;YANG Fang;FENG Jin
DOI:
Objective: To study the imaging feature of primary hyperparathyroidism(PHPT) and osteomalacia(OM) on radionuclide bone scan and investigate the value of bone scan in the diagnosis and differential diagnosis． Methods: The whole-body bone scan findings of 46 primary hyperparathyroidism patients and 24 osteomalacia patients who had been proven by pathology or clinical followed-up were retrospectively analyzed. The differences between the two groups in imaging manifestation and laboratory examination were compared． Results: The bone scintigraphy features of hyperparathyroidism were “black skull”, mandible, limb bone cortex concentration generally increased uptake, and if the bone imaging showed rib punctate concentration, spine strip concentration, large joint body especially weight-bearing joint radioactive concentration should be more consideration for osteomalacia. The differences of serum alkaline phosphatase, calcium and parathyroid hormone levels between the two groups were statistically significant(P<0.05). Conclusion: Whole body bone imaging can be used as an important imaging method for PHPT and OM, and may be more sensitive and comprehensive to detect brown tumor and false fracture site. Combined with the imaging features and the related laboratory tests, it is helpful to differential diagnosis the two diseases.
