Low back and buttock pain in athletes can be a source of frustration for the athlete and a diagnostic dilemma for the doctor. Sacral stress fractures have been increasingly recognised as a potential cause of these symptoms. As plain radiographs are often normal and the radiation load of an isotope bone scan is substantial, the alternative use of magnetic resonance imaging in the diagnosis of a ...

A 60 years old female patient suffering from neck stiffness with solid irregular anterior neck lump came to ultrasound clinic of Radiation and Isotope Centre of Khartoum (RICK), longitudinal and transverse ultrasound scan (U/S) was done for her both thyroid lobes; ultrasound results showed huge (Rt) thyroid lobe nodule with typical criteria's of malignant nodules (solid , solitary , irregular a...

more frequently further radiological techniques are used to determine the extent and site of any spread. The most often used additional investigations are the plain chest film, followed by the isotope bone scan. These methods detect much of the metastatic disease as the chest and bones are major sites of metastases. Problems do arise however, in detecting local spread involving the chest wall a...

BACKGROUND Myocardial viability in area at risk of acute myocardial infarction (AMI) after reperfusion therapy may be underestimated by the 24-hour images due to reverse redistribution (r-RD). METHODS Subjects were 37 AMI patients in whom Tc-99m pyrophosphate (PYP)/Tl-201 dual-isotope SPECT was positive. The 24-hour delayed scan was performed with only a Tl window. One month later, follow up ...

Numerous articles have been published concerning the reliability and usefulness of 9 9 m Tcpertechnetate scanning to diagnose Meckel's diverticulum. The Meckel's diverticulum is an appendage of the ileum near the cecum. To be demonstrated by scanning, the Meckel's diverticulum must contain gastric mucosa which will actively concentrate and secrete the 9 9 m Tcpertechnetate. Meckel's diverticulu...

Precursor ion scan and multiple reaction monitoring scan (MRM) are two typical scan modes in mass spectrometry analysis. Here, we developed a strategy by combining stable isotope labeling (IL) with liquid chromatography-mass spectrometry (LC-MS) under double precursor ion scan (DPI) and MRM for analysis of thiols in 5 types of human cancer urine. Firstly, the IL-LC-DPI-MS method was applied for...

In 1965 Werner and Spooner described a test of thyroid autonomy which has found wide acceptance in medical practice (1). They found that administra tion of l-triiodothyronine (T-3) in doses of 75 to 150 mcg daily, for seven days, suppressed the thyroid uptake of 131!in normal persons and in most patients with nontoxic goiter. Little or no change occurred in patients with diffuse toxic goiter (G...

A 2800 gram baby boy was born with a prenatal diagnosis of a choledochal cyst; he was admitted to NICU for further evaluation. Clinically he was jaundiced with a palpable abdominal mass in the right hypochondrium. Choledochal and duplication cysts were differential diagnoses. Ultra-sonography by an experienced sonographer or a CT scan is usually sufficient for diagnosis. Communicating duplicati...

-This study demonstrated techniques for visualization of detailed brain anatomy with two dimensional ultrasound. The use of large aperture focused ultrasound transceivers appears to be essential for displaying the outlines of thalamus, internal capsule and substantial nigra in addition to those of the ventricles. The ability to vary grey scale and edge enhancement using either linear or logarit...
