Research urges a new approach to cancer detection

A few years ago, Medhat Osman, M.D., Ph.D., had a patient who was scanned due to a suspicion of lung cancer using positron emission tomography (PET) and computer tomography (CT) technology. The scan came back negative, but the patient then complained of a problem with his leg.

Doppler imaging provides better understanding of muscular dystrophy

A new study presented this week at the American Society of Echocardiography's 16th Annual Scientific Sessions offers new hope to children stricken with Duchene muscular dystrophy (DMD), a degenerative muscular disease characterized by a loss of voluntary muscle control which can eventually affect the heart.

Study examines reasons for unsatisfactory outcomes following deep brain stimulation surgery

A study of follow-up care for patients with unsatisfactory outcomes from deep brain stimulation (DBS) surgery for movement disorders offers insights into reasons for problems and proposes strategies for improved outcomes. The study will appear in the August print issue of Archives of Neurology.

Multisequential MRI approach improves heart inflammation diagnosis

A multisequential approach to cardiovascular magnetic resonance scans that highlight different aspects of heart structure and function may offer a better and safer way to identify potentially deadly inflammation of the heart muscle, according to a new study (PDF) in the June 7, 2005, issue of the Journal of the American College of Cardiology.

Fundamental insights in how amyloid fibers form

Amyloid fibers are best known as the plaque that gunks up neurons in people with neurodegenerative illnesses such as Alzheimer's and Creutzfeldt-Jacob disease--the human analog of mad cow disease.

CT screening lowers negative appendectomy rate from 20% to 3% at urban hospital

Five years ago, the negative appendectomy rate at Massachusetts General Hospital (MGH) in Boston was 20%, but since the advent of CT screening, it has dropped to 3%, say MGH researchers. The negative appendectomy rate measures how often patients with symptoms of appendicitis have their appendix removed and then are diagnosed as not having acute appendicitis.

New dopamine transporter gene findings may be relevant for substance abuse, tobacco smoking, and ADHD

Confirming findings in a previous study, Yale researchers observed an altered availability of the dopamine transporter in healthy persons with a genetic variation linked to substance abuse and attention deficit hyperactivity disorder (ADHD).

High-tech imaging software locates more accurately the abnormal electrical impulses that produce heart arrhythmias

Loyola University Health System is one of the first hospitals in the United States to employ new high-tech imaging software - in conjunction with a three-dimensional cardiac mapping and navigation system - to locate more accurately the abnormal electrical impulses that produce heart rhythm disturbances (arrhythmias). This technology represents a major breakthrough in treating complex arrhythmias.
