Big data and its relevance to medical imaging
"Big data" is a buzzword you'll be seeing a lot over the next few years as your corporate executive team and healthcare vendors incorporate it into their business development activities. Hjalmer Danielson from Ascendian Healthcare Consulting helps give some definition to the term in this new column.

A 65-y-old man with HCC and liver cirrhosis confirmed by MRI. Ga-68 FAPI-46 PET/CT demonstrates increased focal uptake (SUVmax, 13.26, and TBRmax, 2.89) in liver, whereas F-18 FDG-PET/CT scans showed non–F-18 FDG-avid lesion (SUVmax, 3.24, and TBRmax, 1.43), indicated by solid arrows. Additionally, histologically proven adenocarcinoma in colon transversum was identified as pathologic with Ga-68 FAPI-46 alone (dashed arrows).

How best to characterize CT lung findings after radiation therapy
By Kate Madden Yee
Serial chest CT is cornerstone of post-RT surveillance, but "accurate interpretation is critical to avoid misdiagnosis."

Acute radiation-induced pneumonitis after SBRT (65 Gy, four fractions) in a 53-year-old woman with leiomyosarcoma of the uterus with a left lower lobe metastasis manifesting as a small nodule (not shown). (A) Axial dosimetric reconstruction of a CT image obtained for SBRT planning shows the metastasis receiving the maximal isodose (6500 cGy). (B) Axial CT image obtained 12 months after completion of RT shows focal ground-glass and consolidative opacities confined to the treatment plan (arrow). Note that acute lung injury with SBRT typically manifests later than with conventional RT (i.e., >12 weeks after completion of therapy), and in 25% of patients, the first CT manifestations occur more than one year after completion of RT.
