The enormous amount of data generated by sensors and other data sources in modern grid management systems requires new infrastructures, such as IoT (Internet of Things) and Big Data architectures. This, in combination with Data Mining techniques, allows the management and processing of all these heterogeneous massive data in order to discover new insights that can help to reduce the energy consumption of the building. In this paper, we describe a developed methodology for an Internet of Things (IoT) system based on a robust big data architecture.

- The study aimed to validate the Edinburgh diagnostic criteria for identifying cerebral amyloid angiopathy (CAA) in patients with non-traumatic intracerebral lobar hemorrhage (ICH) using CT and MRI scans, excluding genetic factors like APOE status.
- Researchers included 102 patients and found that 36 had CAA, while 46 had non-CAA causes, and they achieved an AUC of 0.760 for the original Edinburgh model, which improved to 0.808 with the addition of cortical involvement as a feature.
- The conclusion supports the use of modified Boston MRI criteria for diagnosing CAA and proposes a new three-variable prediction model to enhance diagnostic accuracy in urgent cases of spontaneous lobar ICH.
Background: Body composition, currently evaluated by computed tomography scan, is related to poor evolution and severity of Crohn's disease (CD). Few MRI studies have been performed, yet it is the most commonly used imaging modality for the surveillance of the disease.
Aim: Evaluate the feasibility of MRI body composition measurement and compare the variation according to the activity of the disease.
Obstructive congenital anomalies of the kidney and urinary tract have a high risk of kidney failure if not surgically corrected. Dynamic renal scintigraphy is the gold standard technique to evaluate drainage curves and split renal function (SRF). To compare functional magnetic resonance (MR) urography with dynamic renal scintigraphy in measuring volumetric SRF and in the classification of drainage curves in patients with congenital anomalies of the kidney and urinary tract.

Our objectives were to analyze the feasibility of magnetization transfer (MT) imaging to assess fistulas and to evaluate its contribution in assessing disease activity.
Methods: During 15 months, all patients referred for perianal fistulas in CD underwent 3T-MRI including diffusion, T2/T1-weighted gadolinium-enhanced sequences and MT sequences (one with an off-resonance saturation pulse of 800 and one with 1200 Hz).
