“…Where T (1⁄2 b) is the biological half-life for 131 I in the human body which equals to 6.3 day as the previous study shows [26][27][28][29][30][31][32][33]., and T1/2p is the physical half-life for 131 I which is 8.04 day. Table 2 displays the correlation coefficient R between the dependent variable (Activity) and the independent variable (beta at 1m), which is equal to (0.723), as well as the square of the correlation coefficient (R square), which is (0.523), which shows the percentage of variation between the two coefficients (moderate dependently), and the ANOVA table, which displays the value of (0.00), indicating a strong relationship between the variable's Activity and beta.…”

Radioiodine-131 (I-131) treats hyperthyroidism and differentiated thyroid carcinoma. In I-131, beta radiation (β−) is utilized for treatment and gamma radiation (γ) is used for diagnostic. This research sought to determine if a patient would be treated by establishing an equation for beta-thyroid cell interaction. The prospective study included 35 thyroid cancer patients receiving I-131 treatment. Beta and gamma readings were taken at different distances and sent to the statistical shop to find the coefficients of change on which the beta reaction depends and the equation that depends on it to find the beta range involved in healing. The strongest equation was R square (98.1%). To measure beta at 1 m, use the equation with a 99% association between variables and independent variables, and improve with ANOVA with a p-value of 0.00 0.05. The equation is: β_1m= -123.893+(0.947*δ) +(0.123*ε) -(0.002*π) -(2.11*Log Gamma). The discrepancy between true beta readings (mean = 1040) and the equation (mean = 1087, p-value = 0.411) is more than 0.05. That indicates the values are same. The equation that measures beta during iodine therapy has been achieved, which is the first step to improved thyroid cancer treatment.

“…Tomography has become widely used in scientific medical research and industry for its nondestructive and high-resolution means of detecting internal structure. This includes a variety of applications in seismic data, digital rock physics, medical modalities such as computed tomography, magnetic resonance, and others [1][2][3][4][5][6][7]. Clinicians can use CT to find and diagnose trauma injuries, identify the location and size of a lesion, identify tumor stages, evaluate diseases, identify the location of blood coagulates, detect pulmonary and heart diseases, and recognize ambiguous stomach disorders.…”

In multi-detector computed tomography (MDCT) abdominal and pelvic CT treatments with intravenous (IV) contrast media (CM), automated bolus monitoring with a fixed contrast enhancement delay was examined. Statistics assess all contrast enhancement variables, including patient data like body weight, cardiac output, and contrast injection settings. This study comprised 100 retrospective and 43 prospective patients. In the first group, the Hounsfield unit (HU) was measured before, 30 seconds, and 70 seconds after CM. The second group measured age, weight, heart rate, systolic and diastolic blood pressure, and creatinine. The radiographer computed CM time based on HU values around 120. The differences in HU levels across groups were used to create an equation for imaging time prediction utilizing auto-mated bolus monitoring. The Bolus Time Equation’s predictors included patient weight, heart rate, creatinine level, and systolic blood pressure, with 34.9% dependency and 59.1% influence on each variable. The equation is trustworthy since the ANOVA test indicated p = 0.002. The computation and study gave the same Bolus Time value with a p-value of (0.992 > 0.05). The first and second groups exhibited very different HU rates (p-value 0.00). The research found that fixed-time improved more than bolus monitoring, which performed better.
