Pancreaticobiliary reflux (PBR) and biliopancreatic reflux (BPR) can be diagnosed by magnetic resonance imaging (MRI)

The pancreaticobiliary junction is a complex structure composed of the biliary and pancreatic ducts, which pass through the wall of the duodenum and lead to the ampulla of Vater, which is itself surrounded by sphincter of Oddi.

Magnetic stimulation to target auditory verbal hallucinations in schizophrenia

Schizophrenia (SZ) is a severe chronic mental disorder characterized by a range of symptoms, potentially including delusions, confused thinking, and hallucinations. One of the best-known symptoms is auditory verbal hallucination (AVH), also known as “hearing voices”, which

A personalised operation to stabilise aortic root aneurysms

Personalised External Aortic Root Support (or PEARS) is the name given to a very specific operation. By taking the exact measurement of the individual person’s aorta from a CT or MRI scan, a replica of their own

Cerebral small vessel disease burden is increased in lupus

The chronic inflammatory disease lupus can involve the brain, including increasing stroke risk for reasons which are not fully understood. Cerebral small vessel disease (SVD) is a disease of the blood vessels in the brain that can

An organic gas instead of inorganic gases for the enhancement of 129Xe magnetic resonance signals through optical pumping

Several new methods have been developed in these two decades in nuclear magnetic resonance (NMR) spectroscopy, which make us accessible to weak signals hitherto unmanageable because of the low sensitivity. Among them, spin-exchange optical pumping (SEOP) can

Cerebellar and brainstem malformations

The development of the cerebellum and brainstem is a highly complex process that involves a large number of genes. Mutations in these genes may cause an abnormal development of the cerebellum and brainstem and result in several

MRI with GBCAs – Practical help to ensure patient safety

Malayeri et al writes: “At present, there is no evidence suggesting that gadolinium deposition in the brain alters neurologic function”. Where is the evidence for this statement? Free gadolinium is highly toxic. Even though no clinical implications

Using electrochemistry to address current needs in micro imaging

When one thinks of microscopy, usually imagined is something like a compound optical light microscope, which dates back before the 1600’s. For hundreds of years following, the optical microscope has served the scientific community by helping visualize

Strong magnets to investigate novel dental implants

Replacing lost natural teeth with dental implants is not a recent technological advancement. The implant history dates back thousands of years and includes the ancient Chinese, Egyptians, Mayans, Celtic and Etruscans civilizations. A variety of attempts and

Visual side-effects in radiation treatment of meningioma

Meningioma is one of the most prevalent tumors in the brain. This kind of tumor arises from the natural layers covering the brain; so it is expected to see this tumor in different locations of brain. There

Understanding how enzyme injection for Dupuytren’s disease works

The fascia of the hand is a thin layer of connective tissue that wraps around the muscles, tendons, and neurovascular constitutions in the palm of the hand, providing structural support and integrity. The palmar and digital fascia

Screening breast MRI in patients with personal history of breast cancer

This study looked at patients who had a personal history of breast cancer diagnosed at a premenopausal age to see if having screening breast MRI provided a benefit to the patient. Patients with a personal history of

Cortisol levels as index for vulnerability to stress

Stress exposure is known to precipitate psychological disorders. However, large differences exist in how individuals respond to stress; whereas some people thrive under stressful situations, others break down and are at risk to develop psychopathology. One important

Routine brain MRIs may not be needed after meningioma surgery

A meningioma is a very common form of a brain tumor that tends to affect elderly patients and women. Most patients with meningiomas do not need any treatment, however, certain groups undergo surgical removal of the tumor.

New MRI method for patients with fast and irregular heartbeats

Magnetic resonance imaging (MRI) takes very detailed pictures of the heart. MRI is very safe because it does not give patients harmful x-rays and is one of the best hospital tests used by doctors to check how

Functional networks of the awake rabbit brain

The brain constantly transmits signals whether during idle wakefulness (i.e., “at rest”) or different behavioral states like cognitively-demanding tasks. Studies using functional magnetic resonance imaging (fMRI) in humans have consistently observed neural networks of coherent activity within
