Experimental: Participants with diagnosis of ALS
Participants with a diagnosis of ALS will receive a single dose of [11C]CPPC (370 megabecquerel (MBq) (X±1 mCi)) intravenously and subsequent positron emission tomography (PET) scan.

Drug: [11C]CPPC Injection
A single dose of [11C]CPPC (370 megabecquerel (MBq) (X±1 mCi)) intravenously and subsequent positron emission tomography (PET) scan.

Experimental: Healthy Participants without a diagnosis of ALS
Healthy participants (without a diagnosis of ALS) will receive a single dose of [11C]CPPC (370 megabecquerel (MBq) (X±1 mCi)) intravenously and subsequent positron emission tomography (PET) scan.

- Safety of use of [11C]CPPC in patients with ALS as assessed by adverse events [ Time Frame: Up to 10 days follow up after scan ]Safety of use of [11C]CPPC in positron emission tomography (PET) neuroimaging of patients with a diagnosis of ALS. Safety will be assessed by number of adverse events during and 10 days after the injection.
- Safety of use of [11C]CPPC in patients with ALS as assessed by a change in neurological status [ Time Frame: Baseline and 10 days after scan ]Safety of use of [11C]CPPC in positron emission tomography (PET) neuroimaging of patients with a diagnosis of ALS. Safety will be assessed by neurological physical exam to determine if there is a change in the findings from baseline.
- Safety of use of [11C]CPPC in patients with ALS as assessed by a change in complete blood count (CBC) test [ Time Frame: Baseline and 10 days after scan ]Safety of use of [11C]CPPC in positron emission tomography (PET) neuroimaging of patients with a diagnosis of ALS. Safety will be assessed by monitoring of the complete blood count (CBC) for a change from baseline that is outside of the normal range.
- Safety of use of [11C]CPPC in patients with ALS as assessed by a change in complete metabolic panel (CMP) test [ Time Frame: Baseline and 10 days after scan ]Safety of use of [11C]CPPC in positron emission tomography (PET) neuroimaging of patients with a diagnosis of ALS. Safety will be assessed by a change in the CMP from baseline that is outside of the normal range.
- Sensitivity of use of [11C]CPPC as assessed by a radiologist [ Time Frame: 1 day ]Sensitivity of use of [11C]CPPC in PET neuroimaging to detect ALS will be determined by comparing the PET images from patients with ALS with those from healthy controls.
