Physician's Guide to Modalities

What to order, when — and where we can do it.

Choosing the right exam usually comes down to the area of complaint, the presenting symptoms and the suspected pathology. This is the reference our radiologists use — filter by body area or search a symptom. Every recommendation links to the exam and says where we perform it.

Asymptomatic adult who meets the USPSTF high-risk smoking criteria

Suspected: Early-stage lung cancer, before symptoms appear

  • Low-Dose CT Lung Screening Annual low-dose CT is recommended for people at high risk of lung cancer. All four eligibility criteria below must be met. all but Bradenton

Age 50 to 80. A 20 pack-year or greater smoking history — packs per day multiplied by years smoked. One pack a day for 20 years, or two packs a day for 10 years, both qualify. Currently smokes, or quit within the past 15 years. No signs, symptoms or history of lung cancer. A symptomatic patient needs a diagnostic CT, not a screening exam. Criteria follow the U.S. Preventive Services Task Force lung cancer screening recommendation.

Best in patients with no symptoms of heart disease. Chest pain needs a diagnostic workup, not a calcium score. Most helpful at an intermediate 10-year atherosclerotic cardiovascular disease risk — roughly 5% to 20%, or a borderline-to-intermediate risk score — where the treatment decision is genuinely uncertain. Useful when the patient and physician are undecided about starting or restarting statin therapy. Generally recommended for adults over 40 who fall in that intermediate-risk band.

  • 3D Mammography An effective screening modality from age 40. We recommend repeating it annually. Palm Harbor, Winter Haven and Brandon

Breast

Prior callback for overlapping tissue on a 2D mammogram

Suspected: False positive from superimposed normal tissue

  • 3D Mammography The layered images let the radiologist separate normal overlapping tissue from a real mass, which lowers the chance of an unnecessary callback. Palm Harbor, Winter Haven and Brandon

Suspected: High-risk screening

  • Breast MRI Recommended annually, usually alongside mammography, for women at high lifetime risk. Palm Harbor only

Schedule premenopausal patients on days 6–16 of the menstrual cycle (day 1 is the first day of the period). That window minimizes normal hormone-driven background enhancement, which can otherwise hide small lesions or make interpretation difficult.

Breast

Newly diagnosed breast cancer before surgery

Suspected: Tumor size, additional foci in the same breast, or disease in the contralateral breast

  • Breast MRI Measures the tumor accurately and checks the rest of both breasts before an operation is planned. Palm Harbor only

Schedule premenopausal patients on days 6–16 of the menstrual cycle (day 1 is the first day of the period). That window minimizes normal hormone-driven background enhancement, which can otherwise hide small lesions or make interpretation difficult.

Breast

Neoadjuvant chemotherapy underway or completed

Suspected: Tumor response to treatment

  • Breast MRI Performed before, during or after neoadjuvant chemotherapy to see how well the tumor is shrinking. Palm Harbor only

Schedule premenopausal patients on days 6–16 of the menstrual cycle (day 1 is the first day of the period). That window minimizes normal hormone-driven background enhancement, which can otherwise hide small lesions or make interpretation difficult.

Breast

Suspected breast implant rupture or leak

Suspected: Silicone implant rupture and the state of the surrounding tissue

  • Breast MRI Highly sensitive and specific for implant rupture and leakage. Palm Harbor only

Schedule premenopausal patients on days 6–16 of the menstrual cycle (day 1 is the first day of the period). That window minimizes normal hormone-driven background enhancement, which can otherwise hide small lesions or make interpretation difficult.

Breast

Bloody nipple discharge, architectural distortion, or a persistent exam finding after inconclusive mammography and ultrasound

Suspected: An unresolved finding needing problem-solving

  • Breast MRI Clarifies confusing or persistent findings when conventional imaging is inconclusive. Palm Harbor only

Schedule premenopausal patients on days 6–16 of the menstrual cycle (day 1 is the first day of the period). That window minimizes normal hormone-driven background enhancement, which can otherwise hide small lesions or make interpretation difficult.

Ordering notes

  • Give the signs, symptoms or a specific condition as the diagnosis. Payers commonly reject orders whose only stated reason is “rule out”, “evaluate” or “possible” — those describe the question, not the indication.
  • Say whether contrast is acceptable. Where an exam exists with and without, the CPT code differs — the CPT reference lists both.
  • Tell us about implants, pacemakers or metal fragments before the visit; some require a different protocol or rule MRI out.
  • For a claustrophobic, bariatric, paediatric or geriatric patient, ask for the 1.2T High Field Open MRI or the 1.5T Wide Bore.
  • Not sure? Call 727.787.6900 and ask for a radiologist before ordering.
