DCIS (Ductal Carcinoma In Situ)

DCIS is the most common type of non-invasive breast cancer. Ductal means that cancer starts inside the milk duct; carcinoma refers to any cancer that begins in epithelial tissues (structural tissue cells) or other tissues (including breast tissue) that cover or line the internal organs; and “in situ” means “in its original place”. Thanks to Olea Medical’s Breast application, semi-automatic segmentation of the lesion volume and subtraction dynamic phases successively allow a morphological and multi-parametric analysis.

DCIS (Ductal Carcinoma In Situ) Download

Mesothelioma

Mesothelioma is a rare malignant tumor that affects mesothelial cells, a protective membrane that covers most of the body’s internal organs including the pleura, peritoneum and pericardium. This tumor can develop from the membrane that surrounds the lungs (the pleura), the heart (the pericardium), the intestines (the peritoneum), the testicles and the ovaries. The multiparametric study including the DWI, Permeability and Analysis plugins in Olea Sphere®, will make it possible to differentiate the tumor (mesothelioma), fibrosis, pleural effusion and possible hemorrhages.

Mesothelioma Download

Central Nervous System Primary Lymphoma

Primary cerebral lymphomas are mostly non-Hodgkin’s lymphomas of type B to large cells. Cerebral lymphoma can occur at any age, with a peak frequency of around 65 years. It is a malignant tumor that develops in the brain from B lymphocytes from the lymphatic system. Olea Medical’s Brain Tumor Streamlined application allows a morphological analysis thanks to semi-automatic segmentation and a multiparametric analysis.

Central Nervous System Primary Lymphoma Download

Prostate Cancer

MRI is necessary for the pre-operative assessment of prostate cancer. The MRI Protocol is made of 3 sequences: one T2 weighted sequence, one diffusion weighted sequence (DW) and sometimes one dynamic contrast enhanced sequence after gadolinium injection (DCE). Olea Medical’s Prostate application makes it possible to access to morphological information and parametric maps such as ADC. And thanks to our IVIM plugin, diffusion images can be computed for high b values.

Prostate Cancer Download

Sickle Cell Disease

Sickle cell disease (also called sickle cell anemia) is widespread throughout the world. The severity varies widely among individuals, and symptoms can occur from the age of three months. Sickle-cell anemia can be investigated by MRI if the risk of cerebral infarction is suspected (clinical signs, high blood flow in Transcranial Doppler in children). The anatomical MR sequences will show chronic lesions (silent infarcts, signs of small vessel lesions) or recent ones. Olea Vision will enhance the visualization and analysis of the circle of Willis (thin-slab MIP reconstruction or 3D MIP) looking for probable stenosis.

Sickle Cell Disease Download

Brain Iron Overload in Type 2 Diabetes

Type 2 diabetes, also known as non-insulin dependent diabetes, is the most prevalent and most insidious form of the disease, representing 90% of cases. It is well-known that there are bi-directional relationships between the brain, obesity and insulin resistance. Iron overload is significantly increased in obese subjects and iron seems to play a direct and occasional role in the pathophysiology of type 2 diabetes. In MRI, T2 and R2 are sensitive markers of the iron content in tissue. The quantitative study of T2 and R2 in Olea Sphere® makes it possible to estimate iron loading in the brain.

Brain Iron Overload in Type 2 Diabetes Download

GBCAs: Gadolinium-Based Contrast Agents

Gadolinium-based contrast agents (GBCAs) have been considered safe for many years. The disadvantage of GBCAs was faced by patients with severe kidney disease only and it was linked to the development of Nephrogenic Systemic Fibrosis, or NSF. However, recent reports have shown gadolinium accumulation in neuronal tissues and other tissues, including bone and kidney. Olea Sphere® offers several plug-ins to limit or avoid the use of contrast agents.

GBCAs: Gadolinium-Based Contrast Agents Download

Parotid Gland Cancer

The parotid glands are the largest of the three pairs of salivary glands (sublingual and submandibular glands are the other two). Parotid tumors are rare and often benign, but they may be malignant. Olea Sphere® offers a multiparametric analysis and display (Permeability maps, T1, T2, ADC) which makes the simultaneous analysis of the information provided by MRI easier. By placing a region of interest (ROI) at the center of the tumor, quantitative values that characterize the tumor can be obtained.

Scoliosis

Scoliosis is a three-dimensional abnormality that occurs when the spine becomes rotated and curved sideways. The condition is characterized by a local (vertebrae) and global (spine) deformity pattern, simultaneously altering the vertebral shape and the spine balance and posture. ln Olea Vision™, the CPR (curvilinear reconstruction) functionality allows to reconstruct a new plane following a path defined by the technician. In the case of scoliosis, this will allow better analysis in a corrected image.

Scoliosis Download

Epilepsy in Sturge Weber’s Syndrome (SWS)

Sturge-Weber syndrome, also called neurocutaneous angiomatosis, is a congenital vascular malformation characterized by facial capillary malformation, with variable ocular and neurological disorders. The estimated incidence of SWS is 1 case per 50,000. MRI imaging is useful for the diagnosis and evaluation of brain damage in SWS. In our Olea Vision™ module, MPR (Multi-Planar Reconstruction) and MIP (Maximum Intensity Projection) are particularly adapted to visualize and analyze the data.

Facial Nerve Schwannoma

Schwannoma or neuroma of the facial nerve is a rare benign tumor. It represents between 0.2 to 1.5% of cases of all intra-petrous tumors. Olea Sphere® offers a multiparametric analysis and display (Permeability maps, T1, T2, ADC) which makes the simultaneous analysis of the information provided by MRI easier. By placing a region of interest at the center of the tumor, one can thus obtain quantitative values that characterize the tumor.

Facial Nerve Schwannoma Download

Ischemic Stroke Physiopathology

Stroke is defined as a sudden-onset neurological deficit caused by ischemia or hemorrhage in brain. Ischemic stroke represents approximately 87% of all strokes, it is caused by the localized occlusion of a vessel leading to a cessation of oxygen and glucose supply to the brain, resulting in a collapse of metabolic processes in the affected territory. Olea Nova Move™ allows to visualize dynamic contrast agent arrival to the brain tissue. This "pseudo-angiography" effect can be used to identify an occlusion of one of the main intracranial arteries as well as the collateral circulation status.

Tuberculous Meningitis

Tuberculosis remains a common disease worldwide. After a period of decline, its incidence is growing again, and resistant forms develop. It usually occurs in the young adult, with a majority of cases before the age of 30. Brain Tumor module within Olea Sphere® provides quick access to all perfusion maps, ADC and anatomical exam sequences. The fusion of anatomical images and calculated maps improves the visualization and the relevance of the analysis of the pathological zone. Olea Vision™ module provides good visualization and analysis of small lesions.

APT CEST Brain: Glioma

Multiparametric MRI in brain tumours is an invaluable methodology for obtaining in-depth information for the structural and functional tissue features guiding the differential diagnosis and assisting the tumour staging. Each MRI parametric maps provides crucial information for the different histomolecular tumour substrates, whereas the ‘tier-like’ interpretation of the combined structural-functional outputs helps the radiologist to reach an accurate diagnosis.

Amide Proton Transfer weighted imaging reveals a rolandic tumor in a pediatric patient

The young patient presented a first hyperthermic convulsive seizure. One month later, he presented another tonic-clonic episode with left hemicorporeal seizure lasting less than 5 minutes. Another month later, he had a tonic-clonic seizure again, without fever but complicated by status epilepticus. Afterwards, a CT scan showed a right parietal lesion, and he was transferred to the Necker- Enfants Malades hospital for a brain and spinal-cord MRI. The spinal-cord MRI did not reveal any metastases.
