PiB-PET scans show link between poor sleep and Alzheimer's
PET scans using the Pittsburgh Compound B (PiB) radiopharmaceutical have shown a potential link between poor sleep and greater beta-amyloid accumulation, which could lead to Alzheimer's disease in older adults, according to a study published online October 21 in JAMA Neurology.

PET shows link between arterial stiffness and dementia
PET scans show that elderly people with hardening of the arteries are more likely to have beta-amyloid plaque in the brain, even if they show no signs of dementia or Alzheimer's disease, according to a study published online October 16 in Neurology.

MRA helps detect risk from unruptured cerebral aneurysms
MR angiography (MRA) using a 3D time-of-flight sequence could well be the most efficient technique for detecting unruptured cerebral aneurysms and determining if they pose a health risk, according to a study published in the October 15 issue of Annals of Internal Medicine.

Sports injury website brings radiology's insights to the fans
Ardent sports fans can easily explain a blitz, play-action fake, suicide squeeze, and icing. What many of them can't do is describe a torn anterior cruciate ligament or plantar fasciitis. The founder of a new website, InsideInjuries.com, hopes to change that -- and in the process help educate the public about radiology.

Better training key to unlocking molecular imaging's potential
Molecular imaging has vast potential to improve healthcare in the coming years by allowing more directed, personalized therapy. But molecular imaging's contribution may be limited until more imaging specialists are trained to interpret scans acquired with the new types of tracers being developed.

Preoperative MRI may clarify use of radical trachelectomy
By measuring the distance between a tumor and a woman's internal os at MRI before surgical removal of the uterine cervix, or trachelectomy, physicians may be able to identify high-risk patients who should instead undergo a radical hysterectomy, according to a study published in the October Radiology.

Ferromagnetic detection could boost safety in MRI suite
A ferromagnetic detection system ferreted out many kinds of metallic devices and objects that could typically be introduced into an MRI suite, according to a study in the October issue of the American Journal of Roentgenology. Such a system could help prevent implant-related accidents, the authors concluded.

MRI software opens views to blood-flow issues, stroke potential
When patients experience blood-vessel blockage that could lead to a stroke, correcting the condition as soon as possible can be critical. Vascular analysis technology firm VasSol believes its software, designed to quantify blood flow through any vessel in the body, can help with this and other conditions.

(A) Examples of B-mode images for the measurement of membrane thickness of implants from each of the four types of implants. Images are presented at the same scale. Membrane thicknesses (B) and then shear moduli measured by ARFI method (C) are compared without dissociation as a function of prosthesis age or implantation time. (NS: p-value > 0.05, *: p-value < 0.05, **: p-value < 0.01, ***: p-value < 0.001).

January 19, 2024
F-18 FDG-PET/CT images of patients. (A) Image of a 61-year-old male patient with type 1 autoimmune pancreatitis (AIP) demonstrating diffuse enlargement of the pancreas (arrows). The serum IgG4 level was 2,260.0 mg/dL, and the TLG2.5 was 413.8 g/ml×cm3. According to the nomogram, his relapse probability is more than 95%. The patient discontinued steroid use during the maintenance phase, and 7 months later, he relapsed, with imaging showing diffuse re-enlargement of the pancreas. (B) Image of a 60-year-old male patient with type 1 AIP, showing focal enlargement in the head of the pancreas (arrows). The serum IgG4 level was 980 mg/dL, and the TLG2.5 was 92.7.0 g/ml×cm3. According to the nomogram, the patient’s relapse probability is less than 50%. After symptom relief, the patient did not receive maintenance treatment, and has been followed up for 4 years without relapse. Image courtesy of BMC Gastroenterology.
