Letter to the editor - quantitative serial t2 relaxometry and cerebral cysticercosis.

Sir, the report on "Quantitative serial T2 relaxometry and cerebral cysticercosis" is very interesting (1). Nalini et al. described possible values of quantitative serial T2 relaxometry and cerebral cysticercosis on serial MRI in patients with a solitary cerebral cysticercal lesion (1). This observation might imply a role for quantitative serial T2 relaxometry in cerebral cysticercosis. However, there are many considerations in this report. First, without a control group, it might not be possible to mention that the observed serial change is due to the response to the antiparasitic drug. Second, quantitative serial T2 relaxometry is not routinely used and available. Routinely, the follow-up of a case is simple neuroimaging with the need to use quantitative serial T2 relaxometry (2). The use of radiation-free MRI might be more appropriate for follow-up (3).
