Multislice CT is just as accurate as MRI in assessing myocardial infarct size in an emergency setting, according to a recent study conducted by researchers in France and the U.S. The latest data validate previous findings suggesting delayed-enhancement myocardial CT correlates well with measures of infarction size done with cardiac MR.
Infarct size is one of [...]

Hydronephrosis [water - kidney condition] refers to a kidney with a dilated pelvis and collecting system. It can be caused by obstruction of the ureters or bladder outlet. Hydronephrosis can also result from reflux (retrograde leakage of urine from the bladder up the ureters to the renal pelvis. Rarely, some children have hydronephrosis without either [...]

Diabetes can be dangerous to your feet—even a small cut could have serious consequences. Diabetes may cause nerve damage that takes away the feeling in your feet. Diabetes may also reduce blood flow to the feet, making it harder to heal an injury or resist infection. Because of these problems, you might not notice a [...]

What is a pneumothorax?
A pneumothorax is a collection of free air in the chest outside the lung that causes the lung to collapse.
What are the types of pneumothorax?
A spontaneous pneumothorax, also referred to as a primary pneumothorax, occurs in the absence of a traumatic injury to the chest or a known lung disease. A secondary [...]

While there has been a virtual revolution in the treatment of ischemic stroke thanks to the advent of tissue Plasminogen Activator (tPA), the options for reducing the potential for damage in hemorrhagic stroke are more limited. Nonetheless, progress is being made here, too — especially in the area of prevention.
In addition, new research provides compelling [...]

Owing to its high sensitivity, MRI is the primary neuroimaging modality used to detect and characterize white-matter abnormalities in patients with leukodystrophies.[8,9] Several important contributions of MRI have been recognized.[7] First, MRI shows gross morphology and involvement of different brain structures or tissue classes. Typically, leukodystrophies are associated with increased T1 and T2 relaxation times [...]

A 33-year-old man with a history of recreational benztropine abuse presented to the emergency department with confusion, abdominal pain, and distention. An abdominal radiograph revealed gross fecal loading. He was initially treated with intravenous fluids and opiate analgesia. Subsequently, a diagnosis of anticholinergic poisoning was made, based on tachycardia, delirium, dry mucosa, and reduced bowel [...]

Sound and ultrasound waves consist of a mechanical disturbance of a medium such as air. The disturbance passes through the medium at a fixed speed causing vibration. The rate at which the particles vibrate is the frequency, measured in cycles per second or hertz (Hz). Sound becomes inaudible to the human ear above about 20 [...]
