abstract = {Sodium (23Na) MRI of prostate cancer (PCa) is a novel but
underdocumented technique conventionally acquired using an
endorectal coil. These endorectal coils are associated with
challenges (e.g., a nonuniform sensitivity profile, limited
prostate coverage, patient discomfort) that could be
mitigated with an external 23Na MRI coil.To quantify tissue
sodium concentration (TSC) differences within the prostate
of participants with PCa and healthy volunteers using an
external 23Na MRI radiofrequency coil at 3 T.A prospective
study was conducted from January 2022 to June 2024 in
healthy volunteers and participants with biopsy-proven PCa.
Prostate 23Na MRI was acquired on a 3-T PET/MRI scanner
using a custom-built 2-loop (diameter, 18 cm) butterfly
surface coil tuned for the 23Na frequency (32.6 MHz). The
percent difference in TSC (ΔTSC) between prostate cancer
lesions and surrounding noncancerous prostate tissue of the
peripheral zone (PZ) and transition zone (TZ) was evaluated
using a 1-sample t-test. TSC was compared to apparent
diffusion coefficient (ADC) measurements as a clinical
reference.Six healthy volunteers (mean age, 54.5 years ±
12.7) and 20 participants with PCa (mean age, 70.7 years ±
8.3) were evaluated. A total of 31 lesions were detected (21
PZ, 10 TZ) across PCa participants. Compared to noncancerous
prostate tissue, prostate cancer lesions had significantly
lower TSC (ΔTSC, $-14.1\%$ ± 18.2, P = .0002) and ADC
(ΔADC, $-26.6\%$ ± 18.7, P < .0001).We used an external
23Na MRI coil for whole-gland comparison of TSC in PCa and
noncancerous prostate tissue at 3 T. PCa lesions presented
with lower TSC compared to surrounding noncancerous PZ and
TZ tissue. These findings demonstrate the feasibility of an
external 23Na MRI coil to quantify TSC in the prostate and
offer a promising, noninvasive approach to PCa diagnosis and
management.},
