Usefulness of preoperative breast magnetic resonance imaging with a dedicated axillary sequence for the detection of axillary lymph node metastasis in patients with early ductal breast cancer. Radiol Med. 2019;124:1220–8. Article PubMed Google Scholar Guvenc I, Whitman GJ, Liu P, Yalniz C, Ma...
Visualisation of the detection rates of lymph node metastases according to the used MRI sequences. This bar chart presents the accuracy of the detection for lymph node (LN) metastases in T1 combined with T2 sequence evaluation versus single T1 sequence evaluation showing the overall sensitivities and...
Scanning has been conducted on a whole body 7 T MR scanner (Siemens Healthcare, Erlangen, Germany) using a 32-channel receive head coil (Nova Medical Head Coil, Siemens Healthcare, Erlangen, Germany). The vendor’s product implementation of the MPRAGE sequence12was used to acquire the image...
There was a strong correlation in nodule size between CT and MRI sequences (HASTE: ρ = 0.80, p = 0.003; VIBE: ρ = 0.77, p < 0.001; StarVIBE: ρ = 0.78, p < 0.001). Mean image quality was rated as good to excellent for CT and MRI sequences. ...
Interestingly, standalone FLAIR sequences proved not to be beneficial for the prediction of IDH phenotype, even when combined with DTI. A possible explanation is that T2WI and pre/post contrast T1WI sequences provide complementary information regarding the tumour microvascular proliferation and/or ...
The maximum and minimum values from the phase 2 images are then used to normalize the images at other phases, which makes all intensity values range from 0 to 1 while preserving the intensity change information across time sequences. Limited by the GPU memory, we extract many overlapped 3D ...
PET/MRI were performed on Siemens Biograph mMR (Siemens Healthcare, Germany), which consisted of a 3-T MR scanner and simultaneous PET system without time of flight. Sequences were acquired from the skull vertex to mid thighs in a craniocaudal direction in three-dimensional mode with two and...
To validate a radiomics model based on multi-sequence magnetic resonance imaging (MRI) in predicting the ki-67 expression levels in early-stage endometrial cancer, 131 patients with early endometrial cancer who had undergone pathological examination and
1.5 T and 3 T MRI scans with 4 defined sequences (T2-TSE, T2-TIRM, T1-3D-MPRAGE, and TDI) were performed on a phantom with a CI (SYNCHRONY System by MED-EL Austria) in place. The resulting MRI artifacts were retrospectively compared to MRI artifacts observed in patients with a CI....
In Fig. 2, a flow chart of the steps followed to produce TX-based AC map is shown. A set of PET TX acquisitions was performed post QC-daily normalization routine on a 3.0T PET/MRI system (Biograph mMR Software Version VE11P, Siemens Healthineers, Erlangen, Germany). The TX acquisition ...
