Purpose: To differentiate between the MRI findings for benign bone lesion and metastasis detected by breast MRI in patients with breast cancer and to evaluate the conspicuity of bone lesions according to MR sequences. Materials and Methods: In 14 patients with 15 bone les...
bone, durable local tumor suppression, and effective pain relief. The hollow-perforated screw and nail (multihole injection screw and nail) has central canal and multiple side holes to facilitate injection of bone cement to the bone lesion. An optimal customized surgical option according to the ...
A more extensive study113 on ~400,000 patients from Norway revealed striking variation between breast tumours in the time taken for a lesion to double from 1 to 2 cm, ranging from less than 1.2 months (for the 5% fastest-growing cancers) to 6.3 years (for the 5% slowest-growing tumours...
Brain metastases may present as a solitary lesion or oligometastases. On MRI, the metastases tend to be hypointense to isointense to brain parenchyma on T1-weighted images and hyperintense with peritumoral edema on T2-weighted images. On contrast-enhanced T1-weighted images, the metastatic...
A metastatic lesion on bone scan usually manifestsas a focus of increased tracer uptake but an aggressive tumormay manifest as a photopenic area. Tumors that frequently metastasizeto bone are prostate, lung, breast, renal and thyroid cancersand those with a lower rate of metastatic bone disease ...
With a metastatic lesion, the cancer, begins a “vicious cycle” by secreting factors like PTHrP and other cytokines to stimulate an osteolytic lesion, effectively creating a positive feedback loop that leads to more destruction and weakening of bone. Calcium and other byproducts of the ...
NSCLC is staged according to the American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) system (8th edition) and is grouped into the stage categories shown in Tables 2 and 3 [78, 79]. In the presence of a solitary metastatic lesion on imaging studies, ...
Autopsy was performed on seven cases of malignant tumors and metastasis of the tumors in bone was studied. Five cases out of them were of cancer and the others of sarcoma. The patients ranged in age from nine to sixty-seven years. The metastatic lesion of bone was more extensive than that...
Total tumour volume (TTV = sum of TV of all lesions) and total lesion activity (TLA = sum of SUVmax*TV of all lesions) were calculated for all positive bone lesions on fluoride and PSMA PET/CT. Due to higher reproducibility, SUVmax was chosen for comparison. In ...
PSMA PET/CT findings (Prostate Cancer Molecular Imaging Standardized Evaluation [PROMISE] miTNM stage, lesion location, number of lesions) were collected from the clinical imaging reports and existing databases from the previously listed prospective clinical trials. Statistical Analysis Statisti...
