AGENDA

John C. Hayes, Editor

Point/counterpoint provides food for thought in nuclear medicine

Molecular Imaging Outlook

• Reporter gene imaging illustrates molecular events
• MI explores tumor microenvironment
• FDA seeks ways to streamline review of MI agents
• Cross-sectional imaging correlates with gene expression in renal tumors
• UCLA researchers use F-18 FDDNP to visualize beta-amyloid load in vivo
• Human trial of F-18 galacto-RGD measures avb3 expression of metastatic disease
• MR contrast based on modified HDL enhances atherosclerotic plaques

Overread

• Regulatory issues hamper launch of new PET registry
• Jog-shuttle wheel turns heads and wrists
• Studies explore strategies for emergency room MSCT
• Radiographers lighten load for busy U.K. radiologists
• MSCT and MR compete for intraoperative imaging
• Electromagnetic positioning aids interventional guidance
• MSCT brings ER costs down

Newsclips

• ACR assails cardiology-backed study of utilization
• Ultrasound BI-RADS rates breast lesions consistently
• SENSE imaging helps improve breast MRI
• Lung RFA's midterm results beat expectations
• Cardiac polar mapping could speed diagnosis

Sonography

• Radiology must change to retain ultrasound role

Special: SPECT/CT

• CT starts to shape up as nuclear medicine's best friend
• Oncology benefits from specificity of SPECT/CT
• SPECT/CT imaging raises workflow issues
• High-resolution CT images sharpen cardiac SPECT
• Anatomic road mapping pinpoints infection sites

Special: Nuclear Medicine

• RECIST persists despite flaws
• PET will make SPECT irrelevant in 10 years
• SPECT strengths hold up against PET for long term

Computer-Aided Detection

• CAD's role in breast screening shifts from quantity to quality

Gastrointestinal

• MR contributes to evaluation of pediatric Crohn's disease

Tech Watch

• Next-generation advances push PET/CT into new clinical ground
• InSpace offers one-click bone removal
• 3T head coil offers advanced clinical capabilities in MRI
• Oni gains traction with new high-field extremity scanner
