Ingenia 1.5t mri

All the radiological investigations were carried out at the Institute of Diagnostic Radiology of the “Maggiore della Carità” University Hospital of Novara and all the images were re-evaluated by two independent specialists in Radiodiagnostics, with specific expertise in adrenal pathology. CT scans were performed using a Philips 128-layer Ingenuity CT Elite scanner by 2 mm thickness for each scan, incrementable by 1 mm (128 kV, dose right index 17, mAs 100 and 500). The scan time was 3.3 s with pitch 1.49 and rotation time 0.4 s.
MRI mass acquisitions were performed using a Philips Ingenia 1.5 T MRI using Dixon all black T1 weighted, Dixon in and out-of-phase, TSE T2, T2-Spir and DWI sequences with adc map calculation.
The radiological evaluations at follow-up were performed with the same method used at baseline.

Image acquisition protocol: Magnetic resonance imaging sequences of 83 patients were obtained at our institution using Ingenia 1.5T MRI—Philips™, Amsterdam, The Netherlands and GE Signa 3T M.R.I—General Electric™, Boston, MA, USA with a pre-fixed standard scanning protocol for brain tumor imaging. Patients were duly counseled before imaging. A 16-channel head coil was used. Axial T1 contrast (T1C) and T2W images were obtained from the vertex to the skull base, encompassing the whole brain. For contrast-enhanced T1W images, the rate of contrast injected was 3–4 mL/second and the total contrast injected was 0.1 mL/mmol/kg of bodyweight. These sequences were archived in the institutional Picture Archival and Communication System (PACS) and were exported to the radiomics (texture) analysis software (TexRAD™). The radiological features on the T2W MR images were evaluated and discerned by an experienced neuro-radiologist, TexRAD software was used for segmentation, and the texture features were extracted on the TexRad™ console. The acquisition protocol on the two MRI machines is described in Table 1.
