Low-dose ionizing radiations are commonly utilized in medical centers for diagnostic imaging procedures. Unfortunately, the absorption of ionizing radiation generates reactive chemical species that could damage cells. In diagnostic radioisotope-based imaging procedures, the radiological exposures by gamma emitter imaging probes such as radioactive technetium ((99m)Tc) could express low risk of cancer.

Moreover, the borders of the basal cell carcinoma (BCC) lesions have been challenging borders for the automatic detection methods. In this work, a computer-aided dermatoscopy system was proposed to enhance the clinical detection of BCC lesion borders.

In accordance with the previous study, a (142)Pr capillary tube-based radioactive implant (CTRI) was suggested as a source with a new structure to enhance application of β(-)-emitting radioisotopes such as (142)Pr in brachytherapy.
Methods: Praseodymium oxide powder was encapsulated in a glass capillary tube.
Objective: Many studies have attempted to assess the significance of the use of the β(-)particle emitter praseodymium-142 ((142)Pr) in cancer treatment. As praseodymium oxide (Pr(2)O(3)) powder is not water soluble, it was dissolved in HCl solution and the resultant solution had to be pH adjusted to be in an injectable radiopharmaceutical form. Moreover, it was shown that the nanosized neodymium oxide (Nd(2)O(3)) induced massive vacuolization and cell death in non-small-cell lung cancer.

Therapeutic beams, which are employed in radiation therapy, do not discriminate between normal and cancerous cells and must rely on targeting the radiation beams to specific cells. Interestingly, the application of nanoscale particles in radiation therapy has aimed to improve outcomes in radiation therapy by increasing toxicity in tumors and reducing it in normal tissues.
