Urology
4
Feb

Overview

Urology provides diagnosis and treatment for kidney bladder and prostate conditions with endoscopic surgery imaging guided interventions and oncology collaboration.

Endourology and Stone Management

Minimally invasive techniques such as ureteroscopy and lithotripsy manage urinary stones with imaging guidance.

Oncologic Urology

Prostate bladder and kidney cancer care integrates imaging staging surgery and systemic therapy coordination.

Reconstructive and Functional Urology

Procedures address incontinence obstruction and congenital anomalies with multidisciplinary follow up.

Computed Tomography CT

Feb

Overview

CT acquires multiple x ray projections around the patient to reconstruct cross sectional images. It provides rapid high resolution anatomic detail across the body.

Technique

Modern CT uses helical acquisition multidetector arrays and iterative or AI reconstruction to optimize image quality and dose.

Clinical Uses

Indications include trauma vascular imaging oncologic staging pulmonary embolism evaluation and CT guided interventions.

Limitations and Safety

CT involves ionizing radiation and iodinated contrast risks. Dose optimization and contrast screening are essential.

Positron Emission Tomography PET
4
Feb

Overview

PET images physiologic and metabolic processes using radiotracers such as FDG and detects areas of altered metabolism with high sensitivity.

Technique

Radiotracer selection uptake time and attenuation correction are critical. PET is often combined with CT or MRI for anatomic localization.

Clinical Uses

Oncology staging and response assessment infection and inflammation imaging and neurologic metabolic studies.

Limitations and Safety

Radiation exposure from radiotracers and CT component. False positives from inflammatory uptake require clinical correlation.

PET CT Hybrid Imaging
4
Feb

Overview

PET CT fuses metabolic PET data with CT anatomy in a single session improving lesion localization and diagnostic confidence.

Technique

Accurate attenuation correction and patient positioning are essential. Protocols balance PET uptake time and CT dose.

Clinical Uses

Oncology staging radiotherapy planning and assessment of treatment response.

Limitations and Safety

Combined radiation dose from PET and CT requires justification and optimization.

PET MRI Hybrid Imaging
4
Feb

Overview

PET MRI integrates PET metabolic data with MRI superior soft tissue contrast useful in neurologic and oncologic applications.

Technique

Complex attenuation correction and MR compatible PET detectors are required. Simultaneous acquisition enables temporal correlation.

Clinical Uses

Brain tumor evaluation pediatric oncology dose reduction and soft tissue tumor characterization.

Limitations and Safety

High cost limited availability and complex workflow. MRI contraindications still apply.
