Left Temporal Lobe Scarring

Figure 2. MRI and 18F-FDG transaxial images in a patient with recurrent glioblastoma multiforme. The MRI shows an extensive area of abnormal signal in the right temporal lobe (arrow) in a patient with a suspected recurrent glioblastoma. The 18F-FDG image shows recurrent tumor only anteriorly (arrow). The lower part of the abnormality seen on the MRI scan is therefore scar (arrowheads).

chest and axilla will usually show focal uptake in the sentinel nodes of the axilla and internal mammary chain within 30 minutes (Fig. 3). The site of the sentinel node can then be marked on the skin and subsequently identified at dissection using a gamma probe. In this way a limited number of axillary lymph nodes are removed, sparing the patient a complete axillary lymph node dissection.

In one series, lymphatic nodal mapping had an accuracy rate of about 40% for the radioactive technique; 2 false negatives were identified at surgery and at axillary lymph node dissection, 4 patients had false positive images associated with histologically negative nodes. However, in other series the success rate in identifying

Acne is a name that is famous in its own right, but for all of the wrong reasons. Most teenagers know, and dread, the very word, as it so prevalently wrecks havoc on their faces throughout their adolescent years.
