Protocols used

Patient history

Ultrasound at 22 weeks of pregnancy showed an intra-uterine cyst, diagnosed as multicystic renal dysplasia (both kidneys). MR was performed on 9-month-old infant to characterize the inter renal-splenic lesion.

Procedure

Complete free-breathing examination with Body Navigator and Respiratory Trigger is useful for pediatric patients. Turbo LAVA Flex with Navigator allows for correct timing without breath-hold. This is crucial to detect the arterial phase for lesion characterization. DWI with high b-value shows clear delineation between the cyst and the lesion.

MR findings

The MR exam confirmed the presence of bilateral renal dysplasia and showed a lesion at the level of the left adrenal gland which was not seen on the previous ultrasound exam. Visual was enhanced after gadolinium injection at arterial phase; suspicious of a neuroblastoma.

Available for both 1.5T and 3.0T, it provides high resolution DWI scans, especially useful when the region of interest is small in the phase encode direction.

Clinical benefits:

• Reduces distortion at air/tissue interfaces, e.g., bowel

• Provides a higher spatial resolution diffusion via smaller FOV

• Helps detect and evaluate small lesions that maybe obscured by distortion

• Reduces motion contamination outside the region of interest

Case Study: High Resolution Pancreas Imaging with FOCUS DWIClinical solutions

System: Discovery™ MR750 3.0T Coil used: 32 channel Torso

Patient history

41-year-old patient presented with severe abdominal pain. CT exam revealed an enlarged corporeo-caudal portion of the pancreas. Patient was referred to MR to check for pancreatitis.

Procedure

The eDWI image showed an increased signal in the tail of the pancreas. The FOCUS eDWI b500 image did not exhibit a hypersignal of the nodular lesion. FOCUS with increased spatial resolution helped clearly depict the pancreas from the nodular lesion. Progressive contrast uptake of the tail of the pancreas served as a fibrosis indicator and suggested autoimmune pancreatitis with no risk factor for a 41 year old.

MR findings

The hyposignal of the pancreas tail on the LAVA Flex series suggests pancreatitis and MRCP revealed a discrete dilatation of the Wirsung canal upstream the lesion. The clinician's final diagnosis was suspicion of a pancreatitis autoimmune type II, with a focal lesion in the tail of the pancreas.

Patient history

An elderly patient was referred for an MR exam of a left breast lesion after mammography and ultrasound. The lesion appeared to be markedly hypoechoic on the ultrasound exam.

Procedure

The DISCO sequence improved spatial resolution compared to standard DCE imaging. The DISCO Flex or Single Echo options provided tailored CNR.

MR findings

A 9mm spiculated lesion was noticed in the infero external quadrant of the left breast, corresponding to the lesion seen at mammography and ultrasound. Clinician suspects a high grade ductal carcinoma. Also noticed two additional small lesions, located in the upper breast, at the junction of external quadrants.

Confirmatory imaging results

Ultrasound-guided biopsy confirmed three locations of invasive ductal carcinoma.

Protocols used

Patient history

58-year-old patient with elevated Prostate-specific antigen (PSA) (10ng/mL). MR exam 6 years prior was normal. Patient was referred for follow-up and search of suspect target.

Procedure

HyperCube T2 with HyperSense improved the spatial resolution to study the lesion in 3D compared to standard FSE T2 planes. 3D T2 in 5:32 min instead of 3 x 2D planes in 10 minutes. With MAGiC FOCUS DWI, we increased the b2000 DWI resolution (3mm instead of 4mm slice thickness) in lower scan time. The improvements in resolution and SNR facilitate diagnosis on the b2000 with shorter scan times.

MR findings

Prostate of 68 cc. Nodule in the transitional area with hyposignal T2, restricted diffusion, low ADC of 0.9x10-3 mm²/s. The vascularization of the nodule is slightly higher than the rest of the prostate.
